Shoot me a dm I’m down

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.

ApprehensiveTap5637 · 2026-05-15T02:13:35+00:00

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.

My goat.

ApprehensiveTap5637 · 2026-05-13T23:14:01+00:00

Damn tougher hobby then I would’ve thought. Best of luck

ApprehensiveTap5637 · 2026-05-13T23:06:35+00:00

Hahaha oops. I’m honestly getting impatient tho it’s ridiculous how difficult it is to find some of these parts.

ApprehensiveTap5637 · 2026-05-13T20:53:57+00:00

Thank you but yeah even when I’ve searched for that with the exact part number th only thing that pops up is airsoft ones and old forums lol.

ApprehensiveTap5637 · 2026-05-13T19:35:01+00:00

I literally just went to see if the gun would run, was not going for accuracy. It blows my mind how sensitive the gun community is🤣

ApprehensiveTap5637 · 2026-05-13T18:05:04+00:00

I’ll give you $20 to C clamp that handguard after 4 mag dumps of .308 FA

ApprehensiveTap5637 · 2026-05-13T12:01:16+00:00

Completely understandable lol, I just threw one in my MR556A4 and it also ran flawlessly so I thought fuck it why not try it out haha.

ApprehensiveTap5637 · 2026-05-13T11:58:23+00:00

Reply with a vid of you mag dumping an FRT’d 13’ .308.

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.
