I replaced the over sized broken bolt catch with a KA steel one, swapped out the original nozzle with the RATECH npas nozzle, also a ratech hop rubber since I broke the original one,an aluminum buffer with stronger spring, and the rest are just stock.
I dropped in 3 spacers and 2 quarters in the buffer tube to shorten the cycling (hope can last the bolt carrier & nozzle a little longer), and also can speed the gun up a little bit.
The GnP magazines aren't that great, the cool down effect ain't kool at all & they are a bit on the heavy side.
The front is a GnP DD RIS2 9in from wgc for $75, and does not require the special nut that madbull made to mount it onto the gun. The buttstock is by VFC with LMT logo, but since the buffer tube is milspec, so it takes a rubber mallet to bang it on. The front and rear sight are magpul $15 knockoffs, quality ain't that bad, but the rubber mallet is also A MUST to bang those suckers on the RIS. The pistol grip is a magpul moe-k, not as comfortable as the MOE, but I think it looks quite sexy.
The rest of the stuff are just element M3 flashlight (on/off switch no good, its really tight), VFC fake peq box, KA TD front grip, and the AABB eotech style holosight ( this $45 sight can't compare the finish with the hurricane or GnP ones, but it has 0 ghostings).
The gun is not bad at all, except for the gay trademark, thats why I tape it up. Am I going to build another one? possibly not. Why? Buy one and see it yourself.
