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.

Blown away!
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 nice 458/450 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.

as good as its gonna get
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.
