Lct-102 that i just upgraded with new gears, tappet plate, and spring. Also has zci 6.02 innner barrel with flat hop nub and prommy purple bucking. Last i checked it shoots 370-380. The bottom rail is a b10m with zenimei top rail. Dust cover is the lct brand one that I adjusted to not need the leaf sight attachment, comes with a regular dust cover too. Also have a dtk-2 flashhider for it. Can come with 4 or 8 mag brand mags. Message for more info and pictures Will entertain reasonable offers but this is not some cheap gun
