I got this 223 going yesterday, it has been a work in progress for a while now

I imported a AICS compatible bottom metal for it that has 1/4" action screws front & rear

I also imported a light firing pin, Manners stock & 1-8 Muller Works cut rifled barrel for it, it was fluted along with the bolt modifications locally.

It looks & feels great :)

It shoots reasonably well so far considering it isn't bedded & has only had 20 rounds through it

It liked the 80 ELDM's better than the 75, go figure ;)
