Give me a break with Colt parts markup. (Not you personally!)
The Stag Arms bolt is the same thing. Built somewhere between 0-8 miles away, but definitely 100% same specs.
$78 at Arms East, and we will ship it to you for $9 Expedited.
It will work just like a Colt in your Colt.
$217 for a (potentially) Colt bolt? Why?
I just checked Brownells, $169.99 and sold out. Wow.
The same sentiment goes to LPKs. Stag/CMT LPKs give up nothing but markup to the Colt LPK. The only part I know is different is the safety selector. Lot's of the the CMT parts come marked C. Springs are all from the same subs. We sell them at just under $100 (but not for much longer). Colt $250USD with FCG, from Brownells (who are just charging what they're supposed to.) $250USD? Come on.
Back to the question, who makes the $64 one? If it is Stag Arms, buy it. If not, buy it from us.
All the best.
