I have long sold my colt so I can't do a side by side pic, but I will say that the LMT is as good as the colt in terms of fit / finish. If anything, the colt sporter ( h-bar ) I had was far looser fit upper to lower
The LMT I have on 2 different RRA uppers fit very well , not overly tight, just no play. BTW the RRA lower fit is ever tighter ( actually perfect fit ! ) that needs slight pressure to remove. Only downside with the RRA lower is the takedown pin as a result of this tight fit requires noticably more pressure to push out than the LMT does. Small price to pay for a perfect fit
I was going to buy a RRA upper but for another $70 I thought I would try the LMT
Only issue I would say to watch out for is the "standard" LMT trigger is just ok. Once you use the RRA two stage NM, Chip McCormick and other aftermarket you won't go back
It also came with a ERGO grip which was a nice suprise
You can buy the LMT from Questars. highly recommended dealer. Mark is great to deal with . You can choose from their SOPMOD stock and their 2 stage match as well
Here is a pic. Not much different from any other lower . Don't ask me why they say "Law enforcement use only" . Doesn't mean anything here anyways. I think its because LMT generaly doesn't sell lower only to general public in the US .
