welcome, found these in 7rd http://www.jsesurplus.com/asc450bushmas ... azine.aspx

the old Sig mags took 10 I believe, at one time BM had a 9rd.

some guys have used the blue single shot inserts or black followers in standard 223 mags but usually had to roll the feed lips in a little

user error :mrgreen: :mrgreen:

i joke a bit, but in all seriousness - correct your hold. it shouldn't be bruising you if you're making good solid shoulder contact in the pocket and moving correctly with the recoil.

I have been considering a AR UPPER build... :mrgreen: :shock: :D

I also have had good accuracy from a BCA 6.5 G barrel...

My replacement shoots really fine. Many loads under 1moa. My best has been RL15 and a 123 bullet for just over 1/4
Moa for three and just over 1/2 moa for five shots.

Cant ask fror more from a 70$ barrel!!

Mine is a 20” sts fluted.
