I had this old Blackwater surplus Bushmaster lower laying around and figured I would make a build with it for a backup rifle. Brand new free float upper, BCG, mil spec trigger and magpul furniture. HRF magwell (was not an easy install lol) and it only felt right to throw an Aimpoint Comp M2 on it. I wouldn’t say it’s the best of the best but it will get the job done.

Just completed my M400 Tread build. BCM bolt carrier group, Geissele SSAE trigger, Geissele Super 42 buffer and spring, Geissele super charging handle, SIG Romeo red dot, Samson SXT handgaurd, BCM foregrip and DFCO pistol grip. I think it turned out great and it shoots smooth. I know there’s gonna be hate because it’s a SIG but I don’t mind it.

Finnaly got my hands on a SIR rail. GWOT Vibes are strong with this one. Threw on a few goodies.
