did my online form 1's for SBR's on my 5.7 & 10mm Banshee, so now the wait begins.

I'd like some input as to whether or not a mil-spec stock will fit on the receiver extensions (the 5.7 currently has a "CMMG Micro/CQB RipBrace with 5 Position Enhanced Receiver Extension and Ambi Sling Plate" -although I'm confused as the brace has the gear head works logo, so I'm not sure if things were changed at some time during the manufacturing or what & the 10mm has a "CMMG RipBrace with 6 Position Enhanced Receiver Extension and Ambi Sling Plate"

if a mil-spec stock won't fit these, then I'm going to have to buy new extensions & stocks

obviously, I have a bit of a wait until I decide what I'm going to need to buy, but want to start planning things in advance

Images of the 5.7 brace are as follows:

The 10mm looks like a standard carbine buffer tube, so a carbine stock will work.  The 5.7 has a tail hook Mod 2.  You’ll have to replace the brace tube with a real buffer tube, but that’s no problem.  The rear of the receiver is threaded for a regular buffer tube.

Perfect! that's just the information I was looking for: Much appreciated
