Thread: Suppressor changing point of impact by inches

My old MAE 2 tonne suppressor used to cause a 8" poi change from on to off @100

Sweet. I have a pipe reamer at work I'll use. Or get the engineers to use the lathe.

I recall Browning used to offer a barrel tuner called the BOSS basically a weight that you used to slide up or down the barrel to change the point of impact, any weight or pressure on the barrel will change the poi. Just compare shooting a few rounds normally then resting the barrel on the sandbag and see where the rounds go.

I've seen rubber rings out on the range.

I texted my mate and he said that it was inside the barrel not outside centered

Truly 6" at 25 yd ?
Thats too much for barrel flip. Something else must be loose.

My 7mm08 had 10cm change at 100m with suppressor on. Then it went crazy 20 .. 30cm out worse with supp off than on ...
Turned out a scope base screw had come loose and the suppressor was affecting how much unpredictable movement occurred in the mounting. Tightened that one screw and it went back to behaving itself.

Is your gun shooting well with the suppressor off ?

That's what the fella helping me reckoned. 4-6 inches.

It's got iron sights.

Yeah it did a good group for someone who's never shot irons before. Will try against sometime and see if it helps

I've never experienced a difference of poi with or without a suppressor over 600 mtrs except one time when the thread in the suppressor was very slightly off center. I noticed a tiny indent on the muzzle of the suppressor where the projectile was just brushing against.
