"Pleased with the kit only two parts missing and no steel muzzle brake only plastic orange junk
by Erik G. on 06/18/2018
"Excellent kit! So realistic compared to a real AR-15, the fire control group is nearly the same! GBBs are just more complicated so some small delicate work is needed. 2500 BBs through it and still going strong. If you always loved the build it yourself kits for R/C cars but now are into Airsoft like I am, this is the kit for you!

"I will start by saying this is my first gas airsoft rifle. I have a couple gbb pistols but had no rifles. I had no previous knowledge of the inner workings- but, now I do. I was hesitant to buy this kit because of reading negative reviews. However, I really wanted a gbbr but couldn't give my wife a reasonable explanation that made spending $400+ okay. I will end up with that spent, but it's easier to do $20 at a time.
The kit was nicely packaged with all pieces of a particular part grouped together- trigger, hammer, bolt catch etc. I wasn't missing any pieces nor did I have any leftover. The instruction booklet was very helpful, even though there were no written directions. They provided me with an order to the assembly and names of the parts I was assembling. I did go to the internet a couple times and was able to find what I needed. Thanks to having the proper names from the booklet.
I believe the makers of the kit have been reading and listening to the reviews. I was pleased with quality, still not steel, but zero plastic( other than the nozzle). Everything was neatly packaged and I had everything needed except a mag. and wasn't supposed to have one.
In my opinion, this kit is awesome. With a good bit of patience, a file and some sandpaper, you can come out on the other end with a very nice gbbr. Well worth my money and time.
