"On first inspection this kit seemed complete but after I started to assemble this kit I realized that the recoil spring was missing. Easy fix once I called evike, they said they will try to locate it and if they did they can send it out to me, or if they can't find it within 2 days they will accept a return on my kit. I asked if they would just be able to send a replacement spring if they couldn't find the original due to the fact that the kit is mostly together already and the gentleman on the line said that that can be done also. Great customer support, within 15 minutes everything was sorted out.
Some of the internal parts of the kit seem low quality but I was aware of this going into the kit. This gun is a great gun if you want a project, as the assembly is not the easiest, but can be done with the manual and some effort. This is not a kit you will have done in a couple hours though, it's really is a challenge.
You will not need any experience building guns to buy this kit!!!!! Follow the instructions and you will be okay.
The amount of aftermarket and replacement parts for this gun is emense and I do not see myself getting bored of upgrading and changing the gun. I plan of getting more then one upper going at a time so I can have a very dynamic setup depending on the course/game.
The paint on the reciever of the gun is impeccable and I love the finish. G&P has done a great job detailing every part on the exterior of this kit and I am very impressed with the looks so far. If there is one thing I recommend getting with this kit other then the magazine (which is not included) is a rear sight, as the stock one is very poor in my opinion.
Overall- very impressed and happy with this kit and my first purchase on evike! Evike has been very helpful with finding the missing part and no other company has had customer support this good. 8/8 was gr8 m8
"I bought this exact kit 3 years ago, took me a good 6 hours to build it and it did not work once it was done. The magazine I purchased with the kit (since the kit does not include one) was a standard mag by King Arms and it was awful. I picked up a G&P PMAG and the rifle worked pretty well after that, now I have filed the magazine well so it is wider to fit GHK G5 mags and I recommend them over the other two options. Right from the beginning the buffer tooth broke in half so every time I field stripped the rifle the buffer and buffer spring flung out, doesn't effect functionality just annoying. The bolt carrier and nozzle assembly are not very good out of the box so I picked up a King Arms High Power bolt for field play and those work 100% wonderful. I never liked auto on gas rifles so I bent the hammer spring forward so that it's tension is much higher and you can clearly here a loud "clink" when dry fired. This tension makes semi auto fire every time regardless of temperature outside but auto will not work correctly. With a bit of testing i'm sure you can find a perfect middle ground between the two. Over time I replaced the hammer, trigger and auto sear with steel components and would recommend doing so to anyone thinking about these kits but note that if you run a steel hammer make sure it has the roller bearing on top or it can rub the aluminum bolt and cause quick wear. My charging handle broke in half as well so now I need one of those but other than that it functions great on semi and I love the feel of using this weapon in game. I bought a MAGPUL challenge kit as well and that one worked great out of the box, but that was a newer release so maybe these newer kits will work out of the box with just the G&P mags. My hop up and barrel are still stock and I don't mind them at all. The barrel is accurate and the hop up never adjust unintentionally so I love that once it's set it never moves on you. I also leave my barrel stock because if I go tighter that KA High Power Bolt and Nozzle will make this rifle fire in the high 400fps range and that's to high for a CQB size M4. It already is around 400 with .25 gram BBs.
Conclusion, if you want a rifle you can say you built this is a great one. I'll list a recap of what I needed right away.
- G&P PMAG(or modify to GHK G5 mags)
- Steel Buffer Stop(not required to fire but will break)
- Stronger Charging Handle(real steel works with minor grinding of side flanges.
- King Arms High Power Bolt and Nozzle
There are many wonderful parts for these rifles over seas as well, but to get this rifle out on the field these are all things you can do through Evike and some custom work. Hope this review was helpful.
"This is a amazing gbbr if you have tech skill to assemble this rifle its great and if you upgrade the internals to steel and fine tune its a beast i love it and recommend buying it with the exception that the buyers have patience and knowledge of assembling small parts and springs instructions are easy to follow if you can follow a plastic model car or similar instructions you can build this you will need to do some file sanding etc tuning is highly recommended if done right you will love it!!!
