5 excellent

4th one of these that my agency has ordered for dept. owned SBRs. Install is shockingly easy, extremely solid, noticeable weight and profile reduction. Overall extremely pleased

5 Easy install
Posted by Eddie on Sep 10th 2022
The install was very simple and quick and I love the way it looks. Very few options out there for a Sig 516, but I am very happy with this hand guard. Also this reduced the weight by about three ounces. Thank you Midwest Industries!

5 Mlok rail for Sig 516
Posted by Unknown on Nov 17th 2021
As stated in other reviews, the mlok rail system from Midwest, is a perfect replacement. Easy to install, and noticeably lighter

5 Less bulky lighter
Posted by J L on Oct 20th 2021
The mlok system went on like a well fitting glove. Noticable size difference between the old picatinny system and the mlok. Feel of the rifle while shooting with new mlok system is lighter and way less bulky. Worth the money.

5 Sig 516 Hanguard
Posted by Greg Isaacs on Oct 7th 2021
Thank you for giving Sig 516 owners another option besides the Lancer carbon fiber hand guard. The hand guard installation was simple. The quality is top notch, and the staff at Midwest Industries were incredibly nice and helpful. Thank you!

5 Great rail
Posted by John Zelna on Apr 22nd 2021
Nice rail! Lighter than factory, looks awesome, feels great in the hand. I’m new to MLOK coming mainly from quad rails and really like this. The current rail also has a cutout for the Bayonet Lug on the 516 which is awesome.

5 Perfect
Posted by David Garcia on Apr 8th 2021
Just what the doctor ordered. Build quality was exactly what you would expect from a well known manufacturer. Installation was simple. Lock up is extremely solid. Such a huge upgrade over the factory peice. Really need to experienced in order to truly appreciate. If you own a 516, you need this rail. Thank you Midwest Industries for supporting us 516 owners and bringing us out of the stone age.

5 The handguards 516 owners wanted!
Posted by Wil on Apr 1st 2021
These are the handguards I wish would have arrived on my SIG 516 10"! Fit and finish is awesome and light weight. This set now includes cut out for bayonet lug. Easy to take on and off rifle to get at the gas system. One of the best investments I have made for my 516. Hopefully in the future these will come in FDE or RAL8000.
