Received the rail only, there was an issue with the Barrel mounting hardware NOT being included, I contacted Customer service and they took care of the problem and shipped the necessary parts right away.

The rail itself seems to be machined very well, have not installed it due to no mounting hardware as of yet...only time will tell

Very nice product, fast shipping and excellent services. Thanks

This hand guard was one of two I purchased from ohunt. I grabbed a mk12 and the mk18. The mk18 is great and good to go. The mk12 handguard is not. The handguard is three peice and the side mounting scres stripped on 20 inch pounds of force. Ot had up and down wobble and was not suitable for any use.

Disappointed that the vent holes on the rail are diagonal ovals instead of circles like the real mk12 rail, the included barrel nut is almost the same as the real kac barrel nut except the rail bolts onto this nut using only 2 allen screws on the sides, resulting in the barrel easily flexing up and and down inside the hand-guard. If they had just threaded the bottom mounting whole on the barrel nut and included a third allen **** for the bottom then i think this rail couldve been usable, but as it stands the rail shifts vertical position with just finger pressure making it unusable.

The hand guard is just to loose .no real good way to modify the two bolts going threw it or modify the handgaurd for tight fit

The rail looks great and is machined very well but the adapter between the barrel nut and the quad rail is not ridged enough. The barrel nut is well made and the quad rail itself is quality but the connection between the two is fragile.

Better quality than expected for the cost. It’s not perfect and could use a little bit of design improvement. There should be more than just 2 screws attaching the rail to the collar. Having the 2 screws directly across from each other with no other screws causes a slight pivot point and needs addressed. I have the knowledge and machines to make the improvements so it will not be an issue for me, but for someone that doesn’t then I would advise the risk is on you. The shipping time was longer than expected and could use some improvement. Since I can make my own improvements easily I would purchase again if needed.

These handguards are styled after the incredibly stout Knights Armament MK12 Mod 1 handguard. They look nice, but the mount is kinda sloppy, it flexes up and down quite a bit. I think this can be fixed by adding two additional screws vertically that are like the horizontal mounting screws that thread into the barrel nut. Side to side, there is little to no play. This handguard is just fine to use if you don't mount a laser aiming device on the handguard, but being styled after the MK12, those were used on some rifles. Just my two cents and I may thread the top and bottom to see if it fixes the movement issue. If you re design this handguard with the added mounting screws, I would be interested in trying it out. Overall, it is IMPOSSIBLE to beat the price and the black anodizing is perfect, not too shiny like some other anodized parts out of CN.
