PTS Centurion Arms rail systems are fully licensed replica free float handguards. Centurion Arms is owned and operated by a former Navy SEAL, and these rails are designed to put up with abuse.
The Centurion Arms CMR, or Centurion Modular Rail, is a modular handguard that includes a proprietary barrel nut and is free floated for accuracy. The CMR features dual QD sling swivel sockets on both sides. The locking screws are threaded into steel inserts for maximum reliability. Two anti-rotation tabs fit around the upper receiver to properly index and eliminate all play in the rail hanguard. The side and bottom of the handguard feature threaded holes for accessory and grip panel mounting. The forward 3 mount holes feature steel inserts for maximum durability on accessories like PEQs or flashlights.
The 12.5 inch CMR rail from PTS is an ideal fit for M4 CQB or carbine barrels, and fits over the included low profile gas block.
