  • the lever 70 is pinned to the lower receiver immediately behind the magazine well and above the trigger guard mounting location 91. This location permits sufficient clearance within the trigger guard area for an operator to insert his or her finger within the trigger guard area even wearing gloves and yet permit the operator quick and easy access to the release lever.
  • the lever 70 may define a magazine catch 73 at one end that operatively connects to or contacts the tabbed portion 81 of the AK-47 magazine 30.
  • the magazine catch may define an angled cut 75 or chamfered end to permit it to catch and operatively release an AK-47 magazine.
  • the magazine catch end 73 also defines an elongated slot (shown in Figs. 12 and 14) which serves as a clearance cut to permit the mounting of the torsion spring used to bias the lever 70.
  • a magazine catch 73 There are numerous AK-47 magazine manufacturers making different AK magazines having different sized and shaped tabs with different dimensions.
  • the angled cut 75 or chamfered end of the magazine catch 73 is designed to accommodate all of these magazines and their different shaped tabs, and thereby permit the use of these different magazines with the firearm 10.
  • the other end 77 of the ambidextrous release lever 70 extends and wraps around the trigger guard.
  • the end 77 directed toward the trigger is also angled relative to the magazine catch end 73 of the lever (as shown in Fig. 12) so that it extends substantially parallel with the trigger (and forward of the trigger) when the catch end 73 is engaged with the tabbed portion of the magazine (as shown in Fig. 30), and when pivoted toward the magazine well the end 77 will wrap around or straddle the trigger guard (as shown in Fig. 31).
  • the square shaped cut 79 is sufficiently sized to permit the trigger guard to extend between the paddles 89.
  • This design also gives more room within the trigger guard area for an operator to insert his or her finger in the trigger guard even wearing gloves.
  • This location for the release lever 70 permits the operator to easily operate the release lever, and thus drop the magazine with the trigger finger without the operator having to move his or her finger or hand away from the trigger. This can be accomplished regardless of whether the operator is left-handed or right-handed. Serrations 91 may be added to the paddles 89 of the lever to enhance the grip on this surface.
  • the magazine catch lever 70 is shown holding the AK-47 magazine in position within the magazine well.
  • the paddles 89 extend into the trigger guard area but sufficiently forward of the trigger to permit the operator wearing gloves to insert a finger between the trigger and the paddles 89.
  • the lever 70 pivots about pivot pin 71 and the magazine catch 73 moves away from the tabbed portion of the magazine, as shown in Fig. 31. This permits the magazine to now drop down and out of the magazine well along the groove formed in the magazine well.
  • the ambidextrous release lever 70 therefore may be used to hold the AK-47 magazine or similar magazine in the magazine well and also release the magazine from the well upon pressing the paddles 89 of the magazine release lever 70.
  • the lever 70 defines a radius 97 that is concentric with the mounting pin hole 99 used to mount the trigger guard 24 to the lower receiver 12. This configuration permits the lever to move around the mounting pin hole and the paddles 89 to properly straddle the trigger guard 24 as the lever is pressed and the magazine is released.
  • a torsion spring may be used to bias the magazine catch end 73 towards the magazine well.
  • an ambidextrous release lever 100 may be pivotably connected to the lower receiver 12 via a torsion spring and roll pin.
  • the lever 100 may define a magazine catch 102 at one end that operatively connects to the tabbed portion 81 of the AK-47 magazine 30.
  • the magazine catch 102 may define an angled cut that will permit it to catch and permit the operative release of an AK-47 magazine.
  • the other lever end 104 of the ambidextrous release lever extends and wraps around both sides of the lower receiver above the trigger guard opening and above the trigger.
  • the lever end 104 defines a lever arm that is directed above the trigger and is angled relative to the catch end of the lever so that the lever arm extends substantially horizontally above the trigger.
  • This design also gives more room within the trigger guard area for an operator to insert his or her finger in the trigger guard even wearing gloves.
  • This location for the release lever end 104, and the suitable length of the lever end also permits the operator to easily operate the release lever, and thus drop the magazine, with the trigger finger without the operator having to move his or her finger or hand too far away from the trigger.
  • the lever ends 104 define lever arms that are joined together by a bracket 110.
  • the magazine catch 102 extends outwardly from the bracket 110 to engage or catch the magazine tab.
  • the bracket 110 further defines clearance cuts 112 for the lower receiver and a clearance cut 114 for the torsion spring, which is used to bias the magazine catch 102 towards the magazine well.
  • the roll pin will extend through the apertures or holes 116 formed in the bracket to mount the bracket and thus the release lever to the lower receiver 12 of the firearm.
  • the lever 100 pivots about pivot pin 115 located in the hole 116. This causes the magazine catch 102 to move away from the tabbed portion 81 of the magazine, as shown in Fig. 28 at 121. This permits the magazine to now drop down and out of the magazine well along the groove formed in the magazine well.
  • the ambidextrous release lever 100 therefore is an alternative way to hold the AK-47 magazine in the magazine well and also release the magazine from the well upon pressing the lever ends or arms 104 of the magazine release lever 100.
  • a torsion spring 117 may be located in the clearance cut 114 and may be used to bias the magazine catch end 102 towards the magazine well.
  • the ends 104 will bias toward the lower receiver (as shown in Fig. 27) until the lever contacts the cuts 50 formed in the lower receiver (as shown in Fig. 26) which stops the rotational movement of the lever.
  • the magazine catch 102 is now angled and positioned underneath the tabbed portion 81 of the magazine 30 to hold the magazine within the magazine well.
  • the magazine catch 102 may be angled approximately 110 degrees relative to the lever ends or arms 104.
  • This angle of the magazine catch combined with the location of the cuts 50 in the lower receiver, results in the end of the magazine catch being in the position within the magazine well to properly contact and hold the AK-47 magazine or similar magazine within the magazine well.
  • Other angles and geometries of the magazine catch relative to the lever arms are possible, including angles between approximately 95 and 125 degrees, and are considered within the scope of the invention.
  • the lever ends or arms extend approximately horizontal above the trigger guard opening on both sides of the lower receiver.
  • the lever arms or ends may also extend at other angles relative to the trigger guard opening and yet provide enough clearance for an operator to insert a finger into the trigger guard opening and still conveniently reach the lever ends or arms to release the magazine from the magazine well.
  • a barrel extension 120 may be used for connecting the barrel 19 to the upper receiver 14.
  • the barrel extension 120 defines a specially designed feed ramp 122 that permits the AK-47 round (i.e., 7.62 x 39 mm cartridge) or similar round to properly feed into the barrel.
  • the feed ramp 122 defines an elongated ramped surface extending from the outer peripheral edge 124 of the barrel extension to the bore surface of the barrel.
  • the width of the feed ramp is wider than typical feed ramps and the angle of the feed ramp is flatter than traditional feed ramps to accommodate the AK-47 round or similar round.
  • the width of the feed ramp is approximately the same distance as the distance between the outer edges of two adjacent locking lugs 128.
  • the feed ramp may also have other widths that permit the proper feed of an AK-47 round or similar round into the barrel.

  • a charging handle 75 Slidably mounted within the upper receiver is a charging handle 75 that is operatively connected to the bolt carrier.
  • the charging handle may include a pair of opposing ears that can be operated by either hand to charge the firearm.
  • the charging handle may mount to a channel formed within the upper receiver and may slide within the upper receiver.
  • the bolt 130 strips a cartridge from the AK-47 magazine or similar magazine mounted to the magazine well and moves the cartridge forward and up the feed ramp and into the barrel 19 as the bolt assembly moves toward a battery position.
  • the user can activate the trigger.
  • the trigger releases a cocked hammer and the hammer strikes a firing pin.
  • the firing pin moves forward and makes contact with the cartridge.
  • the contact between the firing pin and the cartridge causes the cartridge to fire and the resultant explosion forces a bullet out the end of the barrel along a forward path dependent on the direction the barrel is pointing.
  • the resultant explosion also causes the bolt assembly to recoil in a backward direction opposite of the direction of bullet travel.
  • the bolt cam pin riding in a slot on the bolt carrier, forces the bolt to turn and unlock from the barrel extension.
  • the bolt Once the bolt is fully unlocked it begins its rearward movement along with the bolt carrier.
  • the bolt's rearward motion extracts the empty cartridge case from the chamber, and as soon as the neck of the case clears the barrel extension, the bolt's spring-loaded ejector forces the empty cartridge out the ejection port in the side of the upper receiver.
  • a buffer spring opposes the backward travel of the bolt assembly and after the buffer spring is sufficiently compressed, i.e., the bolt assembly is in a recoiled position, the compressed spring moves the bolt assembly forward.
  • the bolt's locking lugs then strip a new round from the magazine and the round is guided up the feed ramp and into the chamber. As the bolt's locking lugs move past the barrel extension, the cam pin is allowed to twist in the groove cut into the carrier and forces the bolt to twist and lock into the barrel's extension. The bolt assembly is now in the battery position and another cartridge can be fired. This process is repeated each time the trigger is pulled and a cartridge is fired.
