Yeah, I got a "Classic Army M15A4 CQB."
I made it into a Mk18 CQB R by adding an Aimpoint Comp M2 replica with a Knight's High Ring, First Factory/ANGS Limited Edition AN/PEQ2A replica (THE best and most realistic replica on the market, PERIOD!), and a Surefire Classic 6 volt with Shock Isolated bezel and 1" ring.
It already came with a M4 RAS, Knight flash hider, Cut down Rear A2 sight, Crane stock, and 10.5" heavy barrel. It's even got a faux gas tube that's visible through the upper vent holes on the RAS!
The CA rail covers blow ass, and don't even stay on, so I replaced them with some real Knight's covers I had laying around from when I had a Knight's RAS.
The hider is a bit larger in outer diameter than the G&P unit that came with the Knight's Suppressor, so I can't swoop Anthony's Knight's can just yet.
It's solid as a rock, the RIS is even more solid than the real RAS I had (and it's not fucking purple!), and the ROF is insane with the 2400 mAh 9.4v (30A Discharge Rate!) I got from Precision Airsoft that is specially made for the CA Crane stocks.
Internally, it's completely stock. I'm going to add a tightbore and spring to get it to 400fps, but not for awhile. This little thing is the nicest stock AEG I've ever paid less than 1100 dollars for.
Pics soon. Some of you have already seen it.
Any questions?
