From what I can make of it, he wanted an adpator tu use 5.56 mags so he could use a low-cap, something about sniper ammo limts.

But then again, your guess is as good as mine.

Oh god my thread got hijacked :(

Don't buy the CA. I did. It crapped out after 2 mags. Turned out to be sector gear crapped 3 teeth. Then I noticed the roller bearin under the sector gear crapped also. Little bearings all in my gearbox. You can get a new gear at wgc in hong kong for 13 usd. I do like the longer piston design. When it was shooting, I was shooting .28's really accurate and far. If you decide on CA, change the bearings to solid bushings asap. For a late reply, I hope this helps you Ronan.

Hahaha, he already bought, and sold ( or in the process of selling) it.

G&P SR-25 URX FTW. i love that gun! so solid and heavy and... solid. feels like a real gun when you pick it up. that thing takes it like a man. shoots just under 400 stock, mmmm.... the mid caps are fine. after you 'break them in' they are quite reliable. i looked at the CA one, meh, never seen one but im really happy with G&P. great internals, and full RIS for great accessories. throw an EOtech on there, maybe a vert fore grip (mine came with one, and 2 rail covers), and you are ready to rock. get the G&P. now.
