This GHK has been a WIP for the previous 9 months. I bought it second hand from a guy I know in Texas, he used it quite often, including at two MSWs. I got the gun and 4 mags for $330, then went back later and got the remaining 6 for $170. Considering these retail at $400 with the mags costing $50 a piece, i considered it a great deal. I like a good project, and this is exactly that. From the day i got it, it was problematic. GHK used a cheap pot metal for the full auto sear so it snapped and made it full auto only. I ordered a new, semi-auto only sear and replaced it, but in doing so I stretched out a spring and made it too weak to cycle. I ordered a new one, but the biggest problem spawned during MSW's Seize Grozny in late January. I was performing maintenance the first night and in the process lost the hop-up nub. Due to going broke purchasing other things, this issue went unaddressed for 7 months, just being fixed in late August. I had attempted making my own nubs, but they weren't solid enough. Through repeated use at MCA indoor, the hammer began to deteriorate and eventually split in two. The bolt carrier was also falling apart, so I finally replaced all of those parts. Now, it shoots 400 exactly with .20s and is back to my main gun. I'll be using it at MSW's Caspian Breakout in late October but for now it is holding strong. The externals include an LCT SKBTR stock, a Zenitco B-10, a bulgarian plum upper handguard, and an SRVV muzzle brake. Pictured it has a PKA-V sight. Overall, GHKs as a whole are extremely tough guns. They have LCT Externals, they fit real AK furniture, while the externals are hit or miss due to the wear put on them, I'm still impressed with how mine held up. It managed to hold together with the hammer broken in two for about a month. I would recommend buying new instead of used just because of how much wear may or may not be on the gun when you get it. I would also recommend replacing certain parts like the sear and hammer with Hephaestus aftermarket parts. GHKs may not be cheap, but they're good guns.
