Abstract
An AR-pattern firearm comprises an upper receiver, a housing positioned above the upper receiver and containing a recoil spring assembly, a bolt carrier assembly positioned in the upper receiver, and a bridge plate operably connecting the bolt carrier assembly to the recoil spring assembly. Discharge of the firearm causes rearward movement of the bolt carrier assembly out of battery and hence rearward movement of the bridge plate which stores energy in the recoil spring assembly, whereupon the stored energy in the recoil spring assembly causes the bolt carrier assembly to move forward back into battery.

An AR-pattern firearm, comprising:
- an upper receiver,
- a housing positioned above said upper receiver and containing a recoil spring assembly,
- a bolt carrier assembly positioned in said upper receiver, and
- a bridge plate operably connecting said bolt carrier assembly to said recoil spring assembly exterior of the upper receiver and housing,
- whereby discharge of said firearm causes rearward movement of said bolt carrier assembly out of battery and hence rearward movement of said bridge plate which stores energy in said recoil spring assembly, whereupon the stored energy in said recoil spring assembly causes said bolt carrier assembly to move forward back into battery.
A recoil assembly for an AR-pattern rifle, comprising:
- a housing adapted to be positioned above an upper receiver,
- a recoil spring assembly positioned in said housing,
- a recoil buffer adapted to be positioned rearward of a bolt carrier assembly, and
- a bridge plate positioned exterior to and rearward of the upper receiver and housing and operably connecting said recoil buffer to said recoil spring assembly.
