I have a US compliant Century receivered L1A1 sporter with a Tapco US pistol grip stock set, 10 metric magazines (5 are Austrian) and magazine speed loader that uses M-14 strippers (none included). It has a soldered on DSA brake and functions 100% reliably. I haven't guaged the chamber, but the ammo that has been through has shown no signs of stress on the brass. I hate to let this go, but I have other things that are priority now. E-mail me for a pic. Thanks for looking!
SOLD pending funds!
