Best bolt I have bought so far

Written on Feb 23, 2022

Meant for a 6mm ARC build that is doing 1/3 MOA with factory ammo after a few tweaks. It is impeccably finished. After some 150 rounds and 3 cleaning procedures not a scratch or sign of ware. Very precise tolerances all throughout from the lugs to the gas rings. It is hardy! Out of curiosity I took apart the extractor assembly. The perfect finish is there too. The spring has the right tension. I am really happy with it. It is like a good set of high end speaker for your stereo. You should never go cheap in barrel and bolt carrier group and the bolt is the heart that gets the kick going.

Great bang for your buck

Presma Thread Protectors are well knurled in a small tight pattern. Finger friendly. Threaded to specs and very well finished. I got both in black and stainless. These look much better than the pictures. Clean cuts show a quality job. They weight 4oz. Not enough to get your barrel harmonics out of whack.
