[QUOTE="Ah1356, post: 1557299, member: 108701"] You are hanging a weight on the end of the barrel, and that will change the harmonics unpredictably. It might create a big POI shift, or a small one, or none, but in general heavier suppressors and flexible barrels have the potential for greater POI shift. I have an 18-in .308 and a 26-in 6.5x47 and I use the same suppressor on both rifles. The .308 has very little POI shift, but with the 6.5x47 the shift if 0.2MILs down and about 0.05MILs right compared to a bare muzzle. I have seen guys with more than twice that POI shift. So long as the POI shift is consistent (and thankfully mine is) it’s easy to account for the difference. [/QUOTE]
