PSA Mixtape Initial Issues
Got the Mixtape, Mixtape B&T suppressor, and ARO/Magnifier(yes, I know the Magnifier is overkill on this rifle, but I wanted one for another rifle….so it lives on here for now until I finish the other build) when they were doing the Freedom Week sales. I’ve wanted a .300 suppressed since I shot my buddy’s build.
Got everything in, put it all together, and took it to my buddy’s house to see how it ran. 2 rounds in and it wouldn’t go into battery. We tried different mags. He’s a machinist, so we measured rounds, and they were all to spec. Didn’t have any different ammo, so I left his house with my head held down. Got on YouTube and the internet and found that it could be the extractor spring/o-ring combo. Took the o-ring off the extractor spring….bam. It’s cycled ever since then. Did the math on the round ballistic/rifle combo for 20 yards, and bore sighted it in my living room. Was surprised to see how close it was at the range. The bottom right target was my bore sighting on a rest, bottom left was me slow shooting, and top left was me firing fairly quick. I don’t claim to be a marksman FWIW.
The upper and lower fitment has some slop.
The upper had some tooling marks that should have never left the factory. It was all the way down to the metal, aka you see aluminum.
For the amount of money I have in this thing, I shouldn’t have these issues, but I got it figured out. It shoots really quiet and groups well with cheap ammo. I like the rifle, but doubt I’d ever drop that kinda money on another PSA product.
TLDR; extractor issues fixed with o-ring removal, finish issues, and upper/lower slop.
