I recently bought a 5.56 LMT piston gun. There isn't a lot of info out there for this specific stick so I thought I put a little out there. I have owned a couple of LMT's and they have all worked great, so when I decided to buy a piston set up it came down to LWRC, PWS, SCAR and LMT. I knew LMT so the decision was over. (It actually took much longer than that - you know, "research.") I've put about 500 rounds through it so she's still basically a virgin but this things really is impressive. Here's why:
No carrier tilt. Not even any signs of it. That's a good thing as LMT pins their buffer tubes to their lowers!
Recoil impulse. If I were blind folded, I might, MIGHT be able to tell the difference between my piston and a DI MRP. There really isn't a nickels worth of difference. I know the SCAR and 416 have short, very different impulses and it takes a little getting used to, not so with the LMT piston.
Speaking of the piston . . . I love the piston system! One turn and whole assembly comes out the front. Super easy and tool-less. (Yes, there's a setting for suppressed.)
Fit and finish: It's an LMT. As with any high-end AR it's top notch. I don't know if it was just mine or what, but there is zero play between the two halves. I'm sure it will loosen with time.
Accuracy: This is kinda silly to do an accuracy review on this type of weapon system but it's everything it should be. Zeroing my EOTech @ 100 with the three power magnifier I could hold 1 1/2 - 2 MOA no sweat with LC SS109.
Faults: Standard trigger. I changed mine out with a Geissele before even taking it out. If you've been living on another planet and don't know, Geissele triggers are the bomb. Just find the right model for your intended use. Buy once, cry once, you won't regret it.
Overall, this is a great system and I would highly recommend it! And of course, what good is a thread with pics!?!
