If you are into small arms history, you must have heard of SPR (Special Purpose Rifle.) The SPR, used by Special Operations Forces of both the U.S. Army and U.S. Navy, is a heavily modified light sniper/designated marksman variation of the AR-15/M16 line of infantry weapons, and is chambered for NATO standard 5.56x45mm ammunition. The first SPR adopted famous PRI Gen I and Gen II carbon-fiber free-float handguard. One very important feature of PRI handguard is its carbon fiber main body. The carbon fiber can stop heat transfer from barrel to the hand guard.
Now, MadBull is proudly introducing fully licensed PRI handguard rails to Airsoft industries.
The models we provide for Airsoft are new generation of PRI rails:
- 1. Gen III Round Free Float Rail in different lengths with side rail panels.
- 2. Gen III Delta Free Float Rail in different lengths with side rail panels.
