My point of impact at 30 yards is all over the place, so its safe to say its clipping pellets.
I've tried 5 different Q-Tec's, and they are all clipping, some more than others.
So there seems to be a problem with my rifle too, and taking off the shroud i got a disappointing suprise....
This piece of aluminium with o-rings in the two grooves is whats supposed to keep the shroud centered on the barrel.
Why is this a problem? Well it would be fine IF this part matched the shroud and the barrel, it does not.
id of shroud is about 16mm
od of aluminium insert is about 15.85mm (so its up to the o-rings to keep things centered, not good)
id of aluminium insert and od of barrel has 5 to 6/100 mm of gap too (not that bad, but i would try to make it a 2/100mm gap)
Im using a digital vernier caliper, so some of the measurements might be a bit off, but good enough to get a general idea of what i think is the problem.
If this isnt the problem, it means the threaded insert for the moderator is the culprit (crossing fingers its not)
I will make a new part "without" gaps to see if it fixes the problem, to be continued
