I thought I would share my experience with my LMT AR15.
LMT AR15 SOPMOD
I have shot:
700 rounds of Federal 55gr surplus with
0 jams of any kind
(regular maintenance every 100-300 rounds, D&H industries 30 round magazines)
And through a cmmg conversion kit:
700 .22 LR hollow points..a mixture of Winchester 555 and Federal Bulk with
1 misfire [winchester bulk]
(bolt assembly, magazine, upper receiver, barrel&chamber cleaned once in between)
Just a data point, for any AR15/M4/M16 nay sayers, AK elitists, and of course, people interested in purchasing an LMT.
