Couldn’t be happier. Looks great, nice and balanced. Not too heavy. Would absolutely buy again or recommend

So far so good!

Shipment was much faster than stated. I have not had a chance to install the rail completely but it’s seems well made and will look and work perfectly!

I order coyote brown/ram and I received a black one and I contacted them and they haven’t responded back regarding the issue.

MK 18 handguard

Surprisingly sturdy. This hand guard is meant for rugged use. The handguard is heavy duty, very durable and very reasonably priced. Other handguards of the same quality cost from $150 to $200 or more. I am more than pleased with my purchase. Every serious AR builder should give the MK 18 handguard serious consideration.

Good quality

Appears to be good quality. However, I was sent the wrong color. I attempted to contact ohhunt to fix this, but no one will return my email.

Great product but beware...

Great product, solid and affordable. Beware though, somehow my credit card number got hacked as soon as I placed my order so minus 1 star for that but the other 4 stars are for the rail itself, it's amazing! I'd buy more stuff but this will be the last time because of the card hacking. I do however want to say that it was shipped fast and got it in no time so there's that.

Unnecessarily good

Kinda shocked at the build quality. Installation was identical to the real thing, lockup is solid, top rail is exactly in spec with the upper, and the finish is great. Have to give props to the machinists on this one, nothing looks mangled or out of place. Exact copy. I’ve spent this much on a G**tec MLOK rail and gotten far less quality, and they’re US made! Small concerns about it being 6061 vs. 7075, but only time will tell. For now it works perfectly on my range toy, and definitely scratches that itch for less than 1/4th of the name brand. Probably going to buy another before word gets out and the prices go up.
