LU-MC68-1604: CMMG M4-LEPII 6.8 SPC II Flat Top
AR15 M4 Upper - 16" 1/11 Twist w/A2
Bird Cage
CMMG M4-LEP-II 6.8mm Gas Piston systems operate cleaner then the direct
gas
impingement operating systems. With the piston system, the propellant
gases that
are being diverted at the gas block are now vented at the gas block,
instead in
the operating system of the upper receiver. Since the fouling from the
gas
system is not being vented in to the action of your firearm, it stays
cooler and
cleaner. Our system is designed around the short stroke piston
operation. The
piston pushes the anti tilt one piece carrier, which unlocks the bolt
and allows
the piston to return home while the bolt carrier continues to cycle
independently. All uppers have been factory head spaced
and test fired.
Exception: Does NOT fit Colt Sporter Match H-Bar
The upper is built off of a CMMG standard forged A3 flat top receiver with M4
feed ramps. 4150 steel barrel, M4 profile, 6.8x43mm SPEC II chamber and bore, 1/11 twist ratio and 5/8x24
threaded barrel. The upper includes M4 handguard caps, M4
heat shield lined handguards and an A2 flash hider installed
with a crush washer.
The piston gas block has a gas shut off setting for use with a suppressor to
allow for maximum noise reduction. You must replace the crush washer with a peel
washer if you plan to mount your suppressor on the original flash hider.
Fits on
any standard Mil-Spec lower receiver.
