Sorry for being offline for so long, we have been buried in work.
The story on the S.A.B.R.E. is a long one, we submitted the first sample over 18 months ago 7 months later Tech branch gave a "thumbs down" , we then made some changes per the
ATF letter, resubmitted a physical sample and on Christmas eve 2012 we received a letter and success!
It fires from an open bolt, is locking breech gas piston system similar in design to the rare open bolt M16 design and one of the reasons we received approval I believe is that the recoil/buffer spring is not located in the upper.
It is an amazing advancement for the mac family, upper is machined T6 aluminum anodized and uses ar barrels with our modified gas piston system attached.
