RPTR 10"

Absolutely love this handguard. Will definitely use STNGR handguards in all my builds from here on out.

A slim profile with plenty of attitude. Built like a tank and beautiful to boot

I have been building rifles for 10 years now. I have tried many "affordable" options when it comes to rails and I kick myself each time I do not go with a BIG name on the parts list. I came across this rail in an advertisement and decided to give it a go based upon several reviews. The ordering process was simple and it was delivered very quick. My initial impression out of the box was that the rail was light, machined well and finished well. Once installed I was nothing short of impressed. This rail is light yet very durable. I have put my gear through its paces on many occasions and so far it has not deviated or deformed despite my best efforts. The company is very quick to respond and they seem to get the need for service after the sale. I will be purchasing more of these rails for future builds without a doubt. You will not be disappointed on this one.

Love it great quality and price

This was my first purchase from STNGRUSA and I am extremely satisfied. It arrived quickly and the finish and quality are excellent. The price blew me away. I will definitely be coming back for more.

Awesome handguard!!

Hawk hand guard

Easy to install, no timing needed. Looks great on my AR. I will buying another. Quality materials

Fantastic product

Very nice looking item, smoothed edges, Magpul front sight fit well and the quick disconnect in the back for the sling doesn't allow the sling loop to rotate more than +- approx 10 degrees, Nice not rotating 360 and getting the sling all twisted. The front quick disconnect hole however doesn't have that feature and is thinner and the quick disconnect flops in that hole in and out as there isn't much meat on that hole. It is just a hole, no cut aways for the ball bearings to sit in like the back one. Maybe get one of those top rail QD !!

Too easy

Install went smooth, fitment and performance where spot on, no problem
