Would you contact the manufacturer Update: Post 24 - Muzzle device issue? Help please

[Eurodriver]

Plain jane chrome lined, free floated AR from a good brand.

Shot from a bagged rest with a Geissele SSA-E trigger and two separate optics (Nightforce and Vortex) on two separate days with 3 separate shooters. This target represents the best it would do:




Would you consider that serious enough to contact the manufacturer? How would you expect them to take care of it, if so?

Eventually, yes. But I'd check barrel nut torque and muzzle device torque first.

This is what I would check if the rifle was on my work bench.

I disassembled it, and the torque on the barrel nut was solid but has to be about 70ft lbs to get the teeth to line up for the gas tube. The muzzle diameter is .224 - exactly the same as it is on another AR I have sitting next to it, so it is not constricted.

The manufacturer has agreed to look it over, but I am going to shoot it one more time this weekend with no muzzle device and several different types of ammo to see if maybe reassembling it has fixed any gremlins that were hiding in the shadows. If it doesn't improve, I'm dropping it in the mail. I will take MM's advice to shoot it side by side with a rifle by the same manufacturer with the same ammo and the same optic.

I would be tempted to slug the barrel and check the bore diameter.

I would be tempted to slug the barrel and check the bore diameter.

I would too, if:

A) I had the tools to do that
B) I had the time to do that
C) The manufacturer wasn't playing ball.

Hopefully they don't send it back like "Shot great for us. Sorry you suck".

I'd try more types of ammo first. Try to source some xtac 55 and hpr w hornady 75 and 55. Or just straight hornady.

Get some 50 tipped or jhp varmit while your at it.

Xtac match has been good for me too.

It is possible you got a friday after noon barrel. Myself personally, I have not had great luck with BH. But that's only me. I know guys that really like their ammo.

[Vegasshooter]

Yes Sir I would. After checking things that Buford pointed out. I have a BCM stainless that will, if I do my part, shoot Speer Gold Dot bonded 55 gr into sub Moa @ 100 yds. Again, and we've talked about this, if I do my part. The combo is capable.

I've also had great luck with Hornady 55 grain Varmit Express. This ammo is sub Moa in several different rifles. Maybe try that ammo. If it won't shoot that, it won't shoot.

All this is just my opinion, but worth a shot before sending the barrel back.

With above poster, 50 gr vmax (or AE black box version), some cbc75 and privi 75gr match.

Fwiw, the prvi groups almost half what 75gr tap did, might be a picky barrel.

If nothing does better, I'd send it back. I wouldn't even bother with 55gr fmjs unless they are Spitzer style.

Is the crown damaged? or the muzzle device some how causing this problem.
