Very nice barrel option - Volquartsen Firearms THM S&W M&P 15-22 Sport Lightweight Threaded Barrel

This is a beautiful barrel. I was surprised how smooth and clean the bore was even after shooting at least a hundred rounds. It is an accurate barrel, very accurate even with CCI SV ammunition. I believe the barrel itself is on par with a good barrel built for quality full-size AR 22 cal uppers because I found shooting one of those that the group sizes were similar. Unfortunately I believe that the MP15-22 is limited by its handguard and receiver set flex because I found that moving from resting the rifle on the end of the handguard, right near the magwell, and on the mag well, each moved the point of impact at 50 yards by about an inch, so a dedicated non-polymer receiver set will be superior in all but the most controlled of rest positions. But that has nothing to do with this barrel. It's beautiful. The Volquartsen folks were very helpful and answered questions several times and also sent me out some parts for free that they didn't need to. Very impressed with the product and even more the company which I would recommend.
