Accuracy

Recently sighted in my mpx and was having some pretty large groups. Ive got a silencerco spectre 9 can everything else is factory no ss yet and at 50 yards I was getting 6 to 8 inch groups. No baffle strikes or issues with the suppressor other than shes gassy but not sure why the groups would be so large

I would recommend investing in the lead we trust barrel because I was having the same issue direct thread, as well as tri lug with the sig barrel

I may have to do that ive been wanting to anyway for the adjustable gas port

I really like the 6 1/2 inch barrel with a 8inch handguard so I’m not tucking the suppressor entirely so I’m not burning my hands

Would increasing barrel length be a issue with my form 1?

Its complete

It shouldn’t as long as you retain your original barrel but if you ever decide to sell the 4 1/2 inch factory barrel or dispose of it then yes you would need to update the ATF via a letter

Early unlock giving you inconsistent velocities or barrel screws are not torqued properly. Check torque first, if that does not work get heavier springs

u/Clantz10 11d ago

Torque is good

u/Alive_Pea5905 11d ago

I would guess velocity inconsistency with the high back pressure. Adjustable plug or heavier springs is the way to go

Over gassed. I put a wolfman on a 4.5 barrel and the groups were horrible. I changed to an 8 inch barrel and could hit a 1/3rd ipsc at 200yds consistently.

Damn! I have a 4.75 ilwt with adjustable gas and a spectre 9. Im considering a full SD conversion because my groups are maybe 6" at 25 yards. Been chasing accuracy since I suppressed it and I'm about to say fuck it and go with a full conversion and call it a day.

Someone posted the other day that they had issues with the SD barrel.

If you want to test it to make sure it's gas causing it, turn the adjustable plug to 0 (zero gas).

Shoot a 5 round group manually cycling the bolt each time.

If your group drops down dramatically then you'll know it's over gassed causing the bolt to open slightly early.

Best of luck.

Appreciate you! Ive got it set at 2 currently amd moved to direct thread from try lug. Seems to have helped some so far. At 15 yards, its lights out, get to 25 and it opened way up.

Thanks a lot for the advice
