- The various embodiments and aspects disclosed herein relate to a replacement front sight assembly for a rifle.
- An AK-47 is a rifle first developed in the USSR by Mikhail Kalashnikov. AK-47 rifles are typically low tolerance rifles that have significant fitting issues. One of the most common problems on the AK-47 is a canted front sight. As shown in
FIG. 1 , the stock front sight is mounted to the barrel of the weapon. The front sight is a strut that is pinned to the barrel with a center post that can be shifted to the left or right independent of the outer ring to allow for windage. A centered strut typically provides an aligned sight picture, as shown inFIG. 2A . Unfortunately, some struts are canted to one side or the other so that when the post is centered to the rear sight, the strut is shifted to the extreme left or right, as shown inFIGS. 2B and 2C . In extreme cases, the post cannot be shifted far enough so that the point of aim and the point of impact are not aligned. - Accordingly, there is a need in the art for a method and device to improve the front sight of the rifle.
- A front sight assembly is disclosed herein which replaces a stock front sight assembly to provide a proper front sight picture (see
FIG. 2A ) when the front and rear sights are sighted in. The front sight assembly includes a barrel mount and a gas block mount stacked upon each other vertically. To mount the front sight assembly, the barrel mount may be disassembled so that the barrel mount may be disposed over and eventually secured to the barrel. The gas block mount may be fabricated from a unitary material with the barrel mount. The gas block mount may be slipped over an upper portion of the gas block by partially disassembling the firearm. The barrel mount is snugly fit about the barrel so that the front sight assembly may pivot about the barrel mount, and more particularly, a central axis of the barrel. A front sight may be mounted to the top side of the gas block mount. To adjust for windage, set screws in the gas block mount may be used to pivot and fix the front sight assembly to the left or right about the central axis of the barrel to sight in the front sight. - More particularly, a replacement front sight for an AK-47 is disclosed. The replacement front sight may comprise a gas block mount, a barrel mount and a front alignment member (e.g., front post). The gas block mount may have an upper aperture for receiving a gas block of the AK-47. The gas block mount may have left and right lateral adjusters (e.g., screws, set screws). The barrel mount may be attached to a bottom side of the gas block mount. The barrel mount may have a lower aperture for receiving a barrel of the AK-47. The front alignment member may be attached to an upper side of the gas block mount for alignment with a rear alignment member of a rear sight of the AK-47. The left and right adjusters may be adjusted to sight-in the front alignment member and the rear alignment member so that the point of impact coincides with the point of aim of the AK-47.
- The gas block mount and barrel mount may be fabricated from metal, composite, plastic or combinations thereof.
- The aperture of the gas block mount may have a continuous circular inner periphery.
- The barrel mount may comprise an upper bracket and a lower bracket. The lower bracket may be removable from the upper bracket for mounting the barrel mount to the barrel of the AK-47 without disassembly of the barrel of the AK-47.
- The left and right adjusters may be disposed about a vertical midpoint of the gas block mount on opposed sides of the gas block mount.
- The left adjuster may be a set screw threadably engaged to a left threaded hole in a left side of the upper body. The right adjuster may be a set screw threadably engaged to a right threaded hole in a right side of the upper body.
- The aperture of the gas block mount may have a circular inner periphery and an inner diameter of the inner periphery may be about 0.1875 inches greater than an outer diameter of an upper portion of the gas block to provide for lateral adjustment of the front alignment member.
- In another aspect, a replacement front sight for straightening a canted original front sight of an AK-47 is disclosed. The replacement front sight may comprise a gas block mount, a barrel mount and a mount. The gas block mount may have an upper aperture for receiving a gas block of the AK. The upper body may have left and right lateral adjusters. The left and right adjusters may be adjusted to sight in the front alignment member and a rear alignment member of a rear sight of the AK-47. The barrel mount may be attached to a bottom side of the gas block mount. The lower body may have a lower aperture for receiving a barrel of the AK-47. The mount is used to attach a front alignment member to the gas block mount. The mount may be secured or attached to an upper side of the gas block mount.
- In another aspect, a method for replacing a canted original front sight of an AK-47 is disclosed. The method may comprise the steps of removing a gas tube from a gas block of the AK-47; loosening left and right adjusters of a replacement front sight; disposing a gas block mount of the replacement front sight over a gas block of the AK-47; securing a barrel mount of the replacement front sight over a barrel of the AK-47; attaching the gas tube to the gas block of the AK-47; and tightening and loosening the left and right adjusters to sight-in the replacement front sight of the AK-47.
- In the method, the sighting in step may comprise the steps of aligning a rear alignment member, a front alignment member and an object downrange; taking at least one shot; loosening the left adjuster and then tightening the right adjuster if the point of impact is left of the point of aim or loosening the right adjuster and then tightening the left adjuster if the point of impact is right of the point of aim.
- In the method, the step of securing may comprise the steps of disassembling upper and lower halves of the lower body; disposing the upper half over the barrel of the AK-47; and tightening the upper and lower halves together to secure the lower body to the barrel of the AK-47.

front sight assembly 10 of an AK-47 12 is shown, which is a replacement for a stock front sight of a AK-47 12. Thestock front sight 54 may be removed from the stock AK-47 12 and replaced with thefront sight assembly 10. Thefront sight assembly 10 is mounted to abarrel 20 andgas block 22 of the AK-47 12 to provide better alignability of thefront sight 14 of thefront sight assembly 10 to arear sight 24 of the AK-47 12. Thefront sight 14 of thefront sight assembly 10 may be adjusted left and right to allow for windage. This resolves the problem of canted front sights for AK-47s. A proper site picture is maintained between thefront sight 14 and therear sight 24. Moreover, a post 16 of thefront sight 14 is never shifted to the extreme left or extreme right of the outerperipheral member 18 of thefront sight 14. Rather, the post 16 of thefront sight 14 is centered within the outerperipheral member 18 since the entire outerperipheral member 18. - Referring now to
FIG. 3 , thefront sight assembly 10 includes abarrel mount 26, agas block mount 28 and thefront sight 14. Thefront sight 14 may be removably detachable to thegas block mount 28 as shown inFIG. 3 by way of a picatinny rail or integral therewith as shown inFIGS. 7 and 8 . Referring back toFIG. 3 , thebarrel mount 26 may have a ring configuration. The barrel mount 26 may be traversed between an opened position and a closed position. In the opened position, the barrel mount 26 of thefront sight assembly 10 may be disassembled so that thebarrel mount 26 may be disposed around thebarrel 20 without significant disassembly of the AK-47 12, as shown inFIG. 5 . By way of example and not limitation, thebarrel mount 26 may have anupper half 30 and alower half 32. The upper and lower halves (or brackets) 30, 32 may be removably attachable to each other with threadedfasteners 34 which are received into threadedholes 36 formed in theupper half 30 of thebarrel mount 26. To mount the barrel mount 26 to thebarrel 20, the threadedfasteners 34 are removed from the threadedholes 36 of theupper half 30 of thebarrel mount 26. Theupper half 30 may have a semicircular inner periphery which corresponds to the circular outer periphery of thebarrel 20. Thelower half 32 is aligned to theupper half 30. The threadedfasteners 34 are engaged to the threadedholes 36 of theupper half 30 by feeding the threadedfasteners 34 intoholes 38 formed in thelower half 32. Moreover, the upper andlower halves flanges 40 withinterface surfaces 42 that are parallel to each other. The threaded holes 36 of theupper half 30 and theholes 38 of thelower half 32 may be formed in theflanges 40. - The
gas block mount 28 may be formed from a unitary material with theupper half 30 of thebarrel mount 26. By way of example and not limitation, thegas block mount 28 and theupper half 30 on thebarrel mount 26 may be injection molded or machined from a forged or billet material. Thegas block mount 28 may also have a ring configuration. Thegas block mount 28 may have a circular aperture with aninner diameter 44 greater than anouter diameter 46 of an upper portion of thegas block 22 of the AK-47 12. Preferably, theinner diameter 44 is about 0.1875 inches greater than the outer diameter of the upper portion of thegas block mount 28. The oversizedinner diameter 44 of the aperture of the gas block mount 28 permits for lateral adjustments to windage of thefront sight 14. When thefront sight assembly 10 is mounted to thebarrel 20 andgas block 22, the user may utilize left andright set screws 48 in the gas block mount to adjust for windage. Thegas block mount 28 may form a continuous circle. To mount thegas block mount 28 over the upper portion of thegas block 22, ahand guard 56 andgas tube 58 are removed from the rear sight block and thegas block 22 of the AK-47. At this time, the upper portion of thegas block 22 is exposed and thegas block mount 28 of thefront sight 10 may be disposed over the upper portion of thegas block 22. - The
front sight 14 is shown as being removably attachable to the barrel mount 26 with apicatinny rail 50 or a weaver rail. Thepicatinny rail 50 may be attached to thegas block mount 28. In particular, thepicatinny rail 50 may be fabricated from a unitary material with thegas block mount 28 and theupper half 30 of thebarrel mount 26. Thefront sight 14 will have acorresponding mechanism 52 that is removably attachable to thepicatinny rail 50. - The
picatinny rail 50,gas block mount 20 and thebarrel mount 26 may be vertically aligned so that thefront sight 14 is vertically positioned above thegas block mount 28 when thefront sight assembly 10 is mounted to the AK-47 12. In this regard, minimal windage adjustments are performed when sighting in the front andrear sights - The
front sight 14 is shown as being any HKstyle front sight 14. However, any style offront sight 14 may be incorporated. By way of example and not limitation, the various styles offront sights 14 that may be incorporated are ghost ring, bead, cross hair, post or any of a number of rifle sights. - To mount the
front sight assembly 10 to the AK-47 12, thestock front sight 54 is removed from thebarrel 20 of the AK-47 12 by removing two pins. Referring now toFIG. 4 , thestock front sight 54 is removed from thebarrel 20. Thereafter, thehand guard 56 andgas tube 58 are removed from thegas block 22, as shown inFIG. 5 . At this point, the upper portion of thegas block 22 is exposed so that thegas block mount 28 may be disposed over such upper portion of thegas block 22. To do so, theset screws 48 are loosened so that theset screws 48 do not interfere with thegas block 22. Since the aperture of thegas block mount 28 is oversized, thegas block mount 28 should freely sit around the upper portion of thegas block 22. Additionally, thelower half 32 of thebarrel mount 26 is removed from theupper half 30 by way of removing the threadedfasteners 34. In this way, theupper half 30 of thebarrel mount 26 and thegas block mount 28 may be positioned on thegas block 22 and thebarrel 20. After positioning thegas block mount 28 on thegas block 22 and theupper half 30 of thebarrel mount 26 on thebarrel 20, thelower half 32 of thebarrel 20 is secured to theupper half 30 by inserting the threadedfasteners 34 into theholes 38 of thelower half 32 and engaging the threadedfasteners 34 to the threadedholes 36 of theupper half 30 of thebarrel mount 26. Thehand guard 56 and thegas tube 58 are assembled back onto the AK-47 12 as shown inFIG. 6 . The threadedfasteners 34 are tightened so that thebarrel mount 26 does not wiggle about thebarrel 20. Rather, thebarrel mount 26 is snug on thebarrel 20 and can pivot about thebarrel 20. - To sight in the
front sight 14 of thefront sight assembly 10, the threadedfasteners 34 are tightened snugly to prevent thefront sight assembly 10 from sliding left to right or up and down. However, the threadedfasteners 34 should not be over tightened to prevent rotation of thefront sight assembly 10 about thebarrel 20. In other words, thebarrel mount 26 should rotate around thebarrel 20 to allow theset screws 48 of thegas block mount 28 to adjust for windage. - Provided that the shooter is achieving a sufficiently tight shot group of three or more shots, the
set screws 48 may be used to adjust for windage. In particular, if the shot group (i.e., point of impact) is to the right of the point of aim, then theright set screw 48 may be loosened and theleft set screw 48 may be tightened. Conversely, if the shot group (i.e., point of impact) is to the left of the point of aim, then theleft set screw 48 may be loosened and theright set screw 48 may be tightened. This process may be repeated until the point of impact is aligned to the point of aim. - Referring now to
FIG. 7 , a second embodiment of the front sight assembly 10 a is shown. The front sight assembly 10 a has abarrel mount 26 and agas block mount 28. Thefront sight 14 is made integral with thegas block mount 28 in that thefront sight 14 is permanently attached to thegas block mount 28. Thepost 16 a of thefront sight 14 may be changed out as desired by the user. InFIG. 7 , thepost 16 a is a straight post. However, other types of front sight designs are also contemplated and may be changed out. In particular, thepost 16 a is incorporated into a blade 60. The blade 60 is securable to thefront sight 14 by way ofset screw 62 and may be changed out as desired. - Referring now to
FIG. 8 , a third embodiment of thefront sight assembly 10 b is shown. Thefront sight assembly 10 b has thegas block mount 28 and thefront sight 14 made integral with thegas block mount 28. The barrel mount 26 a has a clamshell configuration that can be traversed between an opened and closed position for mounting to thebarrel 20. The clamshell design of the barrel mount 26 a may be tightened by way ofset screw 64. - The above description is given by way of example, and not limitation. Given the above disclosure, one skilled in the art could devise variations that are within the scope and spirit of the invention disclosed herein. Further, the various features of the embodiments disclosed herein can be used alone, or in varying combinations with each other and are not intended to be limited to the specific combination described herein. Thus, the scope of the claims is not to be limited by the illustrated embodiments.
