Perfect for a SupressorReview by Ron
I bought this Seekins Precision MCSR Rail because I wanted to mount a Silencerco Omega inside of the Handguard; it works as expected. I direct threaded my Omega onto a Rainer Arms 8.5 inch Ultra Match Barrel and it sits nicely inside of the 10" handguard. I used it with one of the Seekins Precision IRMT Billet Uppers and it super solid. The round profile is easy on the hands for holding as well. I would buy it again. (Posted on 10/30/2016)

Didn't come with all the necessary hardware, so now have to wait for the missing part from the manufacturer to finish the build, a wasted week. (Posted on 8/20/2016)
Tough To BeatReview by Lance
I've installed a good handful of rails on both AR15s and AR10/LR308s. Opted for this 12" option after a BCM KMR inside diameter failed to work with my CA15 barrel with large .936" diameter gas block. I was (pleasantly) very impressed with this handguard once seeing it in the flesh. Much easier to install and get timed than expected. Ships with 4 shims if I remember correctly. Mount up design is very solid with a total of 8 screws. Also much lighter than expected yet still very solid. No issues putting pressure on the rail with a bag or bipod, etc. I think the only downside to this rail is the rather larger inside (and outside) diameter which is great if you're looking to fit a suppressor underneath, but not needed in most cases if you aren't looking to do that. In my case I needed something to fit a bull barrel diameter. 5/5 would and will buy again. (Posted on 4/27/2016)
Nice productReview by Shawn
This is a great hand guard for the money, I would have given it 5 stars but the barrel nut required a special 2 pin wrench, so I had to alter mine or order a new one, would have been nice if that was stated in the description. But that aside it is well machined and a nice clean hard coating. (Posted on 4/7/2016)
Top Notch QualityReview by Jay
I've learned that Seekins Precision has unbeatable machining and finish to their products. This is no exception. I purchase this in a 15 inch length and it did not disappoint. If you like the style from the pics, you'll love it in person. The only thing that buyers should be aware of is the fit is so tight that you will need to lubricate the interior of the handguard to slide it in and might even need a rubber tip hammer. Yes, it's that tight. However, at least you know that there will be absolutely no movement (especially after screwing down). (Posted on 11/16/2015)
