Looking to trade my LWRCI M6 S-L upper receiver for a 20" DI upper. Colt, Armalite, or anything with a good reputation. Prefer that it didn't have an "A" frame front sight, but as long as it's an A3, I'll consider it. My upper is in excellent shape. Lightweight, mid-length upper with 1/7" barrel, NiCorr treated. Has a MagPul mid-length MOE handguard (FDE) and Impact Weapons Components sling mount which was installed at IWC years ago. I can also include an MOE cantilever rail for your weapon light. Lastly, the charging handle is equipped with a PRI extension and it's capped off with an LWRCI flash suppressor. It's seen approximately 300 rounds without a hiccup.
S&W 5906 (must be excellent)
S&W 6906 (same)
Walther PDP (yeah, I know)
