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.

To be honest I was not expecting much at this price point. I am happy to say I was wrong. This product is well worth your time and money.

Great product, great price point. Measure complete build before ordering your quad rail. I ordered off of barrel size before completing my build so I was a little off on length needed.

The items are good and at good prices and of good quality but shipping by boat is too slow
