VLTOR MUR 1A (Purchased from Strongside Tactical, but my Colt factory charging handle didn't fit, so I sent it to Katie Ryan at VLTOR for inspection. Katie and the VLTOR staff checked the upper receiver for possible "out of specs" issues. It turns out it was the Colt charging handle that caused the problem. So she sent it back right away and with a BCM Gunfighter Charging Handle - Medium Latch. Since then, there's been no issues).

And the rest are photos after the complete build. I might sell my Colt upper receiver/barrel.

Nice rifle, but it seems a waste to pay the premium for a 6920, just to use its BCG and lower.

nice - you should have just built it from the ground up - those vltor lowers looks GREAT on the vltor mur uppers

Yeah I agree. But that seemed like the easiest way to buy a law enforcement rifle in California.

wow!
What a transformation!
good job

Terrible!!

You should send all the take off parts to me for instant disposal.

Haha. I like the sarcasm.

I'm  thinking about a surefire mini scout m300b..what mount are you guys running?
