Abstract

The present disclosure provides systems and techniques for an attachment that can be fastened to a gun. The attachment may include a top surface having a longitudinal axis and an aiming sight that is parallel with the longitudinal axis, a front surface having a latitudinal axis that is perpendicular to the longitudinal axis, the front surface including a muzzle aperture, a left surface, a right surface, and a fastening system. The fastening system may include a first mounting aperture of the left surface, a second mounting aperture of the right surface, and a locking pin capable of being positioned in the first mounting aperture and in the second mounting aperture such that the locking pin fastens the attachment to the gun. The attachment may be fastened to the gun such that the longitudinal axis is parallel with a longitudinal bore axis of the gun.

Claims (27)

1 . A method of affixing an attachment to a gun, the method comprising:

aligning a guide rod of the attachment with a cavity of the gun;

aligning a muzzle aperture of the attachment with a bore of a barrel of the gun;

mating an electrical interface of the attachment with a corresponding electrical interface of the gun, wherein the electrical interface is capable of powering an electrical peripheral component of the attachment;

inserting, based on the aligning the guide rod with the cavity, a protruding rail of the attachment into a complimentary recess of the gun; and

fastening the attachment to the gun by causing a locking pin to extend transversely across a bore axis of the gun and through (i) a first aperture of the attachment, (ii) a first aperture of a frame of the gun, (iii) a second aperture of the frame of the gun, and (iv) a second aperture of the attachment such that the locking pin is in contact with both the attachment and the frame of the gun.

2 . The method of claim 1 , further comprising:

locking the attachment to the gun by rotating the locking pin a threshold amount.

3 . The method of claim 2 , wherein the threshold amount is 30 degrees, 45 degrees, 60 degrees, 75 degrees, or 90 degrees.

4 . The method of claim 1 , wherein the protruding rail is located on an exterior surface of the attachment, and wherein the complimentary recess is located on an interior surface of the gun.

5 . The method of claim 4 , wherein a left surface of the attachment comprises the exterior surface of the attachment, and wherein a grip sleeve of the gun comprises the interior surface of the gun.

6 . The method of claim 1 , wherein the attachment comprises:

an alloy chassis from which the guide rod extends.

7 . The method of claim 1 , wherein the attachment comprises:

an alloy chassis comprising a muzzle aperture with a diameter of at least 5 millimeters.

8 . The method of claim 7 , wherein the muzzle aperture is tapered such that a diameter at a top end of the muzzle aperture located proximate to the alloy chassis is larger than a diameter at a bottom end of the muzzle aperture located distally from the alloy chassis.

9 . The method of claim 1 , wherein the electrical peripheral component is integrated into the attachment.

10 . The method of claim 1 , wherein the electrical peripheral component is capable of being coupled with the attachment.

11 . A method of affixing an attachment to a gun, the method comprising:

aligning a guide rod of the attachment with a cavity of the gun;

aligning a muzzle aperture of the attachment with a bore of a barrel of the gun, wherein the muzzle aperture includes threads that are capable of mating with corresponding threads of a mechanical peripheral component;

inserting, based on the aligning the guide rod with the cavity, a protruding rail of the attachment into a complimentary recess of the gun;

mating an electrical interface of the attachment with a corresponding electrical interface of the gun, wherein the electrical interface is capable of powering an electrical peripheral component of the attachment; and

fastening the attachment to the gun by causing a locking pin to extend transversely across a bore axis of the gun and through (i) a first aperture of the attachment, (ii) a first aperture of a frame of the gun, (iii) a second aperture of the frame of the gun, and (iv) a second aperture of the attachment such that the locking pin is in contact with both the attachment and the frame of the gun, wherein the attachment is configured to be used as a platform for peripheral components.

12 . The method of claim 11 , wherein the mechanical peripheral component is a suppressor with the corresponding threads or a compensator with the corresponding threads.

13 . The method of claim 11 , wherein the electrical peripheral component is a flashlight.

14 . The method of claim 11 , wherein the electrical peripheral component is a laser sight.
