“The Toolcraft 458 socom bolt carrier group works perfectly and solved quite a few of my FTF issues. I recently had purchased a Radical Arms 458 AR and I must say the rumors are true, they have major issues out of the box (DO NOT BUY a Radical Arms 458). With the stock bolt nothing but FTF's and Jams, tried different magazines, tried the magazine modification, etc. Ultimately after replacing the stock bolt carrier group, the factory included magazine worked flawlessly. Now I am in the process of buying more of the factory included magazines which are E-Landers (included to help others) So very satisfied with my purchase from Arm or Ally.”
“This is the 5th 458 SOCOM Toolcraft bolt carrier group I've bought/ used. This one went into a 10 1/2" pistol build for a don-in-law. As with all Toolcraft BCG's, this one works great. My previous builds for myself and family include two 18" rifles, nor 16" carbine, and now two 10 1/2" pistols. With close to 1000 rounds thru them-all together, I've not had any problems with my Toolcraft BCG's. If I ever do, Toolcraft has a lifetime warranty on their BCG's.”
