Firearm receiver with forward assist and bolt catch release
A receiver for a firearm may include a linkage that integrates movement of left and right forward assists. The receiver may include a linkage connecting one or both of the forward assists to a bolt catch. The receiver may included both a connection between the left and right forward assists as well as a connection between one or both of the forward assists and the bolt catch. The receiver may include a linkage connecting the forward assist mechanism with the bolt catch mechanism such that actuation of the forward assist mechanism moves the bolt carrier and moves the bolt catch mechanism from the engaged position to the disengaged position.
1. A receiver for a firearm comprising:
a bolt carrier comprising a notch formed in a surface of the bolt carrier;
a first forward assist comprising: a body section and a thumb pad;
a second forward assist comprising: a body section, a thumb pad, and a tooth that engages the bolt carrier notch;
a linkage connecting the first forward assist mechanism with the second forward assist mechanism the linkage comprising: a first rotatable link connected with the first forward assist mechanism, and a second rotatable link connected with the second forward assist mechanism, the first rotatable link being further connected with the second rotatable link.
2. The receiver of claim 1 wherein the first forward assist comprises an axis of linear movement that is at a first angle with respect to a central axis of a barrel of the firearm.
3. The receiver of claim 2 wherein the second forward assist comprises an axis of linear movement that is at a second angle with respect to the central axis of the barrel of the firearm.
4. The receiver of claim 1 wherein the first rotatable link comprises a first pivot point at a first end and a first slot at a second end, and wherein the first forward assist further comprises a first post that is positioned at least partially within the first slot.
5. The receiver of claim 4 wherein linear movement of the first forward assist imparts rotational movement to the first rotatable link.
6. The receiver of claim 4 wherein the second rotatable link comprises a second pivot point at a first end and a second slot at a second end, and wherein the second forward assist further comprises a second post that is positioned at least partially within the second slot.
7. The receiver of claim 6 wherein rotational movement of the second rotatable link imparts linear movement to the second forward assist.
8. The receiver of claim 6 wherein the first rotatable link further comprises a first link post and a third slot, and the second rotatable link further comprises a second link post and a fourth slot.
9. The receiver of claim 8 wherein the first link post is positioned within the fourth slot, and the second link post is positioned within the third slot.
10. The receiver of claim 9 wherein rotational movement of the first rotatable link imparts rotational movement to the second rotatable link.
11. The receiver of claim 9 wherein:
linear movement of the first forward assist imparts rotational movement to the first rotatable link;
rotational movement of the first rotatable link imparts rotational movement to the second rotatable link; and
rotational movement of the second rotatable link imparts linear movement to the second forward assist.
12. The receiver of claim 11 wherein the rotational movement of the first rotatable link is in a direction opposite to the rotational movement of the second rotatable link.
13. The receiver of claim 1 further comprising a bolt catch rotatable between an engaged position and a disengaged position.
14. The receiver of claim 13 further comprising a bolt catch linkage connecting the first forward assist with the bolt catch.
15. The receiver of claim 14 wherein actuation of the first forward assist moves the bolt carrier in a direction parallel to a central axis of the firearm and rotates the bolt catch from the engaged position to the disengaged position.
16. A receiver for a firearm comprising:
a bolt carrier comprising a notch formed in a surface of the bolt carrier;
a first forward assist comprising a first axis of linear movement that is at a first angle with respect to a central axis of a barrel of the firearm;
a second forward assist comprising a second axis of linear movement that is at a second angle with respect to the central axis of the barrel;
a linkage connecting the first forward assist with the second forward assist such that actuation of the first forward assist along the first axis of linear movement moves the second forward assist along the second axis of linear movement.
17. The receiver of claim 16 wherein movement of the second forward assist along the second axis of linear movement moves the bolt carrier in a direction parallel to the central axis of the barrel.
18. The receiver of claim 17 further comprising a bolt catch.
19. The receiver of claim 18 further comprising a bolt catch linkage connecting the first forward assist with the bolt catch.
20. The receiver of claim 19 wherein actuation of the first forward assist rotates the bolt catch from an engaged position to a disengaged position.
