||I have recently purchased this kit and it is very awesome, after 2000 rounds the only thing to break is the buffer lock, and a steel replacement is only $10 so I can not complain to much. If your are wary of getting this gun because you have to build it DON'T BE!!!! It is extremely easy to put together and I have a very en depth step to step procedure of how to put it together
Easy to assemble.
Two nozzles, one for 300fps and another for 350fps.
Upper and lower receivers may be wobbly against each other, however it varies, in one of my kits the upper and lower meet very tightly and then my other kit has a pretty sloppy fit.
G&P Pmags will need modified to work in the gun, either modify the gun or the mag catch, again this video can be found on my you-tube channel if you want to know how to fix this.
Great looking gun and after you get the mag or mag catch modified it works like a charm! I have nothing but absolutely great things to say about these kits. If you are on the fence about getting one of these kits do it! They are only a fraction of the cost of a assembled one, plus if you put your gun together to start with you will better understand the weapon, and be better able to fix and maintain it in the future.
