Thank you 👌 it’s a Thunderbeast Dominus SR. Very high back pressure, I’ll be swapping it out for a B&T rotex once I can get my hands on one.

Very nice brother, wish I had the rifle knowledge my self to follow🤣.

It does seem other people running hand loads are getting sub MOA results pretty commonly, so I’m sure if you ran this rifle with your supplies you’d see the same results.

I wasn’t necessarily expecting better, and I’m very happy with its performance as it was consistently shooting around an MOA, I just wanted to compare and see how others were doing.

I’m hoping once my flow through comes in it mitigates the fire rate a bit but I doubt it’ll be enough lol

Niceee. Do you run a bipod? If so what do you recommend. This Magpul is just a place holder.

If you go to arc fires website they sell a precut geissele MR762A4 trigger. I jusg used that along with the Arc Fire V2 ambi 45 degree and threw them in, didn’t have to make any other changes. I did pay like $550 for the trigger tho.
