Selling a modded up A&K m16 DMR. Not too far from stock but still has upgrades. Here are all the specs you could ever need for the original gun. https://www.evike.com/products/28236/. However I have added a magpul barrel cover (real magpul not fake). Angel customs tight bore inner barrel (can’t really remember the length but it’s not any longer than the original). Pro - win hop up with a flat hopped bucking. Gun is in really great shape and I have reached out and hit dudes with it at least 100 yards away plenty of times. Would really appreciate if you messaged me before buying.
