Love it! Great product! Would buy more rails in the future!


Works well with the handguard I purchased from Stngr

Low Pro gas block

Quick shipping and delivered in excellent condition. The gas block is a work of art. I would recommend this to anyone.

Excellent Customer Service and an Even Better Product

First, the price is right. I'll gladly pay a premium for American manufacturing. I'm a machinist, myself. However, clocking in at just over 30 dollars this gas block is a steal!

Immediately after installing my new handguard and gas block, which took about 5 minutes due to the genius simplicity of STNGR's designs, I took it to the range to function check it. I dumped several hundred rounds through it immediately and they ALL cycled just fine.

Just for a lark I checked the handguard on a surface plate for parallelism and there was less than a thou of runout over all 15 inches.

Shipping was fast, and their response time to the only inquiry I had regarding my order was less than five minutes... on a Saturday. I don't know how they do it, but STNGR has made a lifelong customer out of me. I don't write reviews, but I'm honestly blown away. What an amazing company. Their products do not compete in quality with "premium" manufacturers. They surpass them. I cannot speak highly enough of their products and their customer service.


It’s a very solid piece! Shipped with my STNGR handguard, so it was packaged well. I have zero complaints! I have joined the swarm!

VYPR 15" KeyMod Handguard

I originally purchased this handguard to replace a factory set of plastic handguards and to change the function of the rifle by extending the handguard out to 15 inch mark. This handguard was way better than I had expected, the Machining quality is excellent with no sign of bowing on the top rail. I was skeptical at first because of the low price but I took a Gamble and it paid off. This is an excellent quality handguard that in my opinion rivals Midwest Industries or any other quality brand for half the cost. I've used this handguard for a while now and put it through some tests and it's held up excellent , the machineday in QD mounts fore and aft saves a little bit of money as I don't have to buy a separate attachment piece for the sling. The barrel nut install was also quite easy and the weight of this handguard is extremely light at a touch over 11 oz . I'm now looking at upgrading two more rifles and I'll be using STNGR USA! what a great company, made right in the USA out of Texas. I wouldn't hesitate to recommend this to any of my friends, as a matter of fact once they look at it and shoot it they immediately want one and want to know where I got it?


Ordered my 13.5 HWK and had it within 4 days. Really like the ability to use Facebook messenger or text message to get accurate and current updates. Also if I had any questions could very easily text back and got an immediate response. I actually already recommended this to a friend and plan on it for many more builds. Great value, great product, and great customer service.
