POI much higher after the R3M kit installed
So after i installed the R3M Kit my POI went up quite a bit to the point that I had to put 4 pieces of coke can (shims) under the front of the scope because my scope would not raise the recticle high enough with out them.
I’m not to concerned about it cuz the thing is shooting so good. Just wondering if anyone can shed some ideas as to what might have changed. Is this a common trait for the R3M’s the breech doesnt seem to be any higher then the R3, and the space between the air resovour and the shroud looks the same. I havent chrony’ed it yet to see if the FPS changed, but like i shoot it Sat and at 70 yds was shooting quarter sized groups.
I bought a new scope (Hawke Sidewinder 30 6-24×56) and used the same 4 shims. I still had to raise the recticles a little from how it came from the factory to get it zeroed.

yes. teflon tape on the barrel breech end or o-ring may help.
You probably changed the barrel alignment when you did the installation. You might want to try loosening and re-tightening the barrel, paying close attention to alignment as you tighten.
Instead of using coke can shims try this. It worked great for me.
1) remove the scope rings and rail.
2) wrap the muzzle end of the rail in heavy cloth or cardboard.
3) put he wrapped end of the rail in a vise and apply some hand pressure to gently bend the rail muzzle end up
4) frequently take the rail out of the vise and lay it upside down on a flat surface to observe if any and how much you have bent the rail. Take your time and don’t over do it.
5) stop bending when the rail has about 1/16 (or less) rise (arch) in it (for scopes that run out of adjustment – poi is high and can’t be lowered any further)
6) remount the scope with the muzzle end ring as close to the end of the rail as possible.
The slight bend is not noticable.
That is it. Good luck.

different barrel nut torques and rear shroud orientation can change POI a lot.. try loosening the barrel torque nut and turn the rear shroud tube a 1/8 to a 1/4 turn at a time and re torqe the barrel nut then test on paper.. you will find it shoots different every time.. set it at the lowest POI.
