Description
This is a proper Mk12 Mod1 clone upper built on a new FN lower. The lower is pretty standard but has a proper Colt buttstock assembly, not a cheap commercial version. The upper is where this rifle shines. It is properly built to military specs for the Mk12 Mod1. It has a proper Doulas barrel, Badger Ordnance gas block that was professionally installed per mil-spec. It has the Allen Engineering brake and collar assembly. The upper has the correct Knight’s Armament long free float rail, which is ridiculously difficult to find. Upper has a correct USMC marked Knight’s folding rear sight already attached, plus an AO Precision BCG and standard carry handle. The upper has a grand total of 40 rounds of Nosler 77gr. match ammo through it. I will include a box or two of the same ammo with it.
If you would be interested in the upper only, I’ll take $1800.00 for it.
I work odd hours and travel a lot, so texts are best. I can be tricky to get in touch with but the upside is that because I travel all over Utah, I can deliver the rifle anywhere on I-15 between SLC and the Arizona border. Utah CWP holders take priority. Feel free to request additional images through text. Thanks for looking!
I would consider a partial trade for a Browning Hi-Power in nice condition, or a new Springfield Armory SA-35 with the high polished blue finish.
