THIS IS THE FINEST BOLT I HAVE PURCHASED IN A LONG TIME, THE QUALITY IS OUT STANDING AND THE FINISH IS EXCELLENT, SHOOTS AND EJECTS FLAWLESSLY THANK YOU SO MUCH!
quick ship, very high quality part. Performs flawless and runs so well in my upper. I have had so many issues with my redical 458 socom upper, this bolt fixed everything! Just in time for my Heli Hog hunting trip! Thanks cobra!
I Ordered this Bolt because I have two already that are useless to me.. really bad feeding issues, one i bought from BCA and the other from Radical. so glad I took a Cobratac parts. evreything worked like a champ from round 1. Such a relief.
ran this on a 458 socom upper that has had so many issues i have pretty much given up on... I have no clue what the voodoo magic is on this bolt but it now runs like hot butter. Save yourself some headache on the advice of someone who has been through hell with a 458 and DO NOT BE STINGY!!! Pay the few extra bucks for the Cobratac 458 socom bolt.
very good quality bolt, Lock up and head space are good, and after 300 rounds of heavy recoiling ( for an AR ) Bushmaster rounds it still going strong.
I have used several of these for 450 Bushmaster builds for deer hunters - no problems. I have bought some for much more expensive and were junk.
no issues with the bolt! Very happy
Used this Bolt to finish my 450 Bushmaster build. Using a Noreen lower , CMT billet upper W/ .458 ejection port, 18in Faxon Barrel using Hornady Custom factory loads I have a sub- moa rifle. All day!
zero problems, works as it is supposed to. Quick shipping thanks Cobratac
