Curious as to how they are using a dust cover on the receiver for the OSSM. They state that the order these from the manufacture and rechamber (an already loose chamber).Hoot wrote:I like the way they avoid mentioning Olympic Arms anywhere in their 300 OSSM product description. I do however applaud them taking the 22" barrel it normally comes with and re-cutting the chamber for accuracy. Mine was loose as a goose with way too much freebore.
I can't believe they've been selling the +P 450 Bushmaster for over a year and no one from here ever noticed. I can't imagine what the bolt is made from, that it can withstand pushing a 300gr bullet at 2500 fps, out of a 17.5 inch barrel, for very long. "...Speeds that would ruin a mil spec rifle."

Only bolt I ever saw that would work for an AR15 in .308 head size was from AR15 Performance. As far as the 300 gr. at 2500 fps ----- pressures got to be up above 100000+ psi. WELL we all know what it can be DONE ONCE!!!!
