Could be better (12/05/2011)

Total junk, the ends are higher to prevent you from mounting stuff at the very end of the rail, so my stuff won't fit. Now I will have to get another rail from another manufacturer. The only reason I don't send it back is the bolts that hold it to the handguard will be needed for the next rail. The rail itself is already in the garbage can.

grade A+++ (24/12/2011)

good design good fitment i would highly recommend for the mounting on the bottom of the magpul hand gaurd

Too thick (20/05/2012)

Excellent polymer material and reasonably well made for its price tag. I do find the part a bit thick for my personal preference adding more bulk to the forearm than necessary once the accessories are installed. I found a good use however on the slim-line Choate 1022 pistol grip stock forearm for mounting light and laser accessories. Its also perfect for the CAA side mounted bipod using this Choate stocks.

Good rail!!! (19/11/2012)

I put this rail on my Sig Sauer AR-15 so I could attach my gripod vertical grip. Works very well. It's nice and soild and works surprisingly well considering the low price.

M.O.E rails buy theses dont go cheap (27/09/2014)

Perfect fit when i add a tac light it is a nice tight fit Beware of cheap impostors i ordered a set of theses on ebay it came with all four sizes 5,7,9,11 but i didnt read carefully it said fits on M.O.E Magpul unit when i got them the set was $13.00 one, the screws were way to long and scratched up the heat shield the the top and bottom halfs would not lock together good think i found the correct screws at work the next day, and the big problem with cheap knock offs is when i put on my tactical light the rail will hold it but it flops around and is not a tight fit when u add your light, fore grip etc so go with magpul, dont go cheap .it could be your life at stake.

i like it (13/01/2011)

i installed it on my m&p15 moe easy to put on strong and looks like factory

Rock solid (30/06/2010)

Great alternative to an AR when you don't want to add a full rail hand guard. Holds VFG tightly

Tough Enough to Handle it all (20/11/2011)

I was concerned that this rail wasn't going to cut it being "plastic" and all. Let me set your mind at ease. They are rock solid and tough. Don't hesitate to buy this.

excellent (02/07/2011)

I used this rail to mount a Streamlight TLR-1s weapon light on my duty AR with the Magpul MOE forend. The combination works together perfectly. The rail is very light and mounts the TLR securely.

Worked Great. (11/09/2011)

Perfect for mounting lights, etc. I mounted this on the bottom of a shortened Butler Creek folding stock for my Ruger 10/22 SBR. Perfection. I liked the first one so much that I ordered three more. I ordered the shortest one and it works perfect. I had to buy longer bolts at [...] because of the thickness of the stock and I used lock nuts with nylon inserts instead of the regular nuts that came with the rail to mount it onto the bottom of the stock. This is a great product.

Great Product (06/11/2011)

At first I was concerned about this being a polymer rail. Once I installed it, all my apprehension went away. Very solid and perfect for small accessories like a small flashlight mount.
