I'll eventually replace the bipod. The thing weighs 9lbs 15 oz as shown.

It's still breaking in, but I'm at 1 MOA with Hornady Black, and 1.5-5 MOA with Wolf Steel cased ammo depending on random flyers.
Wolf Steel cased is frustrating, because I'll string together an awesome 3 or 4 round group and have a random flyer or two nowhere near the main group.


I don't reload, so I'm gradually trying different loads. They're few and far between in my neck of the woods though.

Trigger is good but not phenomenal. It breaks right at 4 lbs, and is polished and adjusted.

Upper receiver was lapped and bedded.

I say this was my 3rd build because I went through 2 BCA barrels before this one to find one that can shoot.

take all the money you spent in ammo testing 3 barrels and breaking them in
and you could have bought a higher grade barrel

was it really worth it?
just curious

[slappyhooper]

Nope. It clearly wasn't.

I still like BCA for common calibers.
I think they're generally great for 5.56/308/300 BLK.

I'll look elsewhere for barrels in different calibers.
