thank you !
This is my LMT lower with my LMT 10.5" upper:
It's wearing a DD Omega Rail, KAC 300M BUIS, Cut Down TD Grip, Magpul MIAD with the large backstrap and a Lightweight RediMag. BCG is full Colt and the charging handle is a PRI Gas Buster.

My 16" Defender all LMT with a few other toys.

Just a bit. As normal as any Colt. In fact I dont notice it at all when I shoot it![]()
I have 2 other RRA lower receivers paired with CMT upper receivers that dont have ANY play between them. Also have another LCW receiver paired with a RRA 9mm upper that excibits almost no play.
I have an LMT upper and an LMT lower, and there's still some play.![]()
It's just part of the design of the weapon, and frankly it's a non-issue. Companies that try to eliminate play between uppers and lowers do so by tightening the tolerances, with no practical benefits whatsoever. It only becomes harder to take the two halves apart, and you might find that uppers from other manufacturers may not even fit the lower.
