AR piston upper with standard m4 handguard?

Re: AR piston upper with standard m4 handguard?

The original LWRC M6 was like that. It's since been discontinued and replaced by the M6-SL, which uses the midlength gas system and midlength Magpul MOE handguards.

Just take a standard DI, retrofit it with a Osprey Defense piston kit...It comes with a standard HG...I did one for a local PD...4500 rounds and they seem to love it...I have one on an M4, works great..

Talk to Matt and Marcy at Northwest Tactical about an LWRCI SL upper, as mentioned by Snake above.

Light, accurate, and sweet.
