Thank you very much, I'll read through that today. Any idea whether a 5.56 bolt will fit in the BCG? Maybe it's addressed in that thread.Ruger SFAR 308 ?
https://ruger.com/products/sfar/models.html Any one know what bolt and extension this uses? An AR15 with a long mag is what I am seeing. Any more info?mdws.forumchitchat.com
That's really useful, thanks! I wonder if the bolt release could be switched to a standard AR one. It looks to me like it's just wider than the standard one. Maybe the MDWS thread will address this question.Although upper and lower pin holes 'would' align, they can't because the bolt release is in the way. Even if you removed half the width of the bolt release, I don't think it'll work on the AR bolt. FCG is in the wrong place plus the SFAR lower is slightly wider than an AR so the upper doesn't sit on the lower properly. I can't close the upper/lower due to the bolt release being in the way but it looks like you'd have a small gap at the rear too.
As far as I can tell , the SFAR and AR bolt locking lugs are different so it's not like you can try swapping them around.
88gr ELDMs and 90gr VLDs require 2.6+" COAL and about .25" freebore. 75gr ELDMs can probably be fired from a standard Wylde chamber and about 2.45-2.5" COAL.What COAL are you hoping for? I've gotten to 2.42 on a standard small frame lower.
