New to airsoft? Here are some safety tips for airsoft guns that we recommend following.

The MadBull PWS Diablo RIS Unit for M4 is an amazingly realistic looking replica of the famous piston driven firing system from PWS. The free float rail system and extremely aggressive compensator give this unit unique form and plenty of function. This is designed for a CQB set up. Madbull is leading the airsoft industry in real gun licenses, this allows them to legally put real gun trademarks on their high quality products. This is yet another excellent quality airsoft replica piece from Madbull.

Product Information:
The Diablo Upper is Primary Weapons Systems’ answer to the 7” AR-15/M-16 series upper. Rather than simply bolting on an existing product and calling it revolutionary, PWS stepped back and designed a system from the ground up to work specifically with the extreme pressures of the 7” barrels.

The Diablo upper utilizes a long stroke piston system for additional dwell time and smooth recoil. The system is rounded out with the new CQB comp from PWS - a comp designed for short barrels that compensates, suppresses flash and directs all the blast forward.

Pros:
Accurate replica.
Clean machining.
PWS Trademarks.
Nice finish.

Cons:
Must use Vltor upper receiver.
Won't work with standard flattop receiver.
Have to mod Magpul XTM covers to fit.
Would not recommend to novice builders.

Product Information:
Contrary to the previous review, I had no problem mounting this to a G&G Combat Machine which I used as a base gun in my project. GI even uses them for making Diablos, so I was weary while deciding on whether to buy this or not, but I did and it fit well. The thing is that you can't just screw it on out of the box. The barrel nut is pre-screwed into the upper body mount, but all you have to do is take off the rails, unscrew the barrel nut, insert the barrel, then screw on the upper body mount. Once you've done that, you can tighten the barrel nut onto the upper body mount. Luckily for me, Madbull included some very detailed instructions on how to mount this.

It was very easy to mount and it is extremely lightweight. You can't go wrong with this one. All together, my rifle ended up being 25 inches long with the stock collapsed. It is shorter than an Mp5a4. If you are looking for a high quality rail system that is easy to install out of the box.

Pros:
Monolithic.
Three QD sling mount ports.
Lightweight.
Compact.
Utilizes a 225-229mm barrel perfectly. (not included.)
Great matte finish.
No wobble once installed correctly and rails are mildly tightened down.
Easy-to-follow instructions.

Cons:
None.
