Blackout build

[Brianb23]

HWanted a bear and cougar gun up here in the NW. Had to be accurate but larger caliber than 5.56.

Aero upper and lower matched set
Rainier arms match grade 16" stainless barrel
Carbine length gas
Geissele 13" mk4 mlok
Geissele stainless gas block
Vltor 7.62 muzzle device
Aero LPK
Aero carbine buffer tube with H buffer
Left over DD butt stock from my v3

Now I just need to save funds for a vxr patrol 3x9 and she will be ready to hunt.

Nice!
I'm wanting to build me a 300BO myself.
Which hand guard are you using? Looks like the one my buddy gave me to put on my AR.

It's the Geissele Mark4 13" I built it using a carbine length gas system so it seems to favor the supersonic loads. Subsonic loads fail to strip a new round. I've switched buffer weights but no luck. Since I'm mostly hunting with it im not concerned.

How accurate is the barrel?

Debating on that or the BA one.

What type magazines are you using? With Pmags the subs were doing the same with my 300 BLK, switched to Lancer mags for my 300 and no more issues.
