Abstract:
In broad embodiment, the present embodiment is a separation limiter, which reduces the possible angle of motion of the upper and lower receivers of an AR-15 style firearm. The present embodiment also reduces the risk of pinching of hands and fingers when pivoting an AR15 style firearm about a front take down pin.

Claim (Index 1):
A device for limiting the separation between the upper receiver and the lower receiver of a semi-automatic gun, comprising a stopper, a hanger and a nut, where the nut has a nut body, a nut hole and nut threads, where the nut threads extend from a first pace of the nut body through a second face of the nut body, stopper comprises a stopper body, a stopper edge and stopper hole, where the stopper hole extends from a front stopper face through a back stopper face, where the hanger comprises a hanger vertical member, where the hanger vertical member has a hanger hole, a hanger inner diameter, a hanger terminal diameter, and hanger threads, where the hanger threads mate the nut threads, such that the hanger terminal diameter can be inserted through the stopper, and the nut can be tightened such that the stopper is retained between the nut and the hanger inner diameter, and where the hanger hole is large enough to allow a Pin Pal body to be inserted through it, whereby a plurity of Pin Pal threads at a terminal end of the Pin Pal body mate with a plurality of Pin Pal nut threads located on the inside of a Pin Pal nut, such that the stopper can be located such that when the stopper edge comes into contact with a handguard assembly of the upper receiver, and where a contact between the stopper edge and the handguard assembly causes the upper receiver to not rotate further in a downward direction.
