"I really love this rail system it cheap, reliable and really strong aluminum. I bought this rail system for my m16 build and it fit the build perfectly. I highly recommend this rail system to anybody, and it is kind of hard to front wired but you can do it, and the paint is not the best so I do recommend buying rail covers as well.

"Bought this rail about a month ago and it was the best 50 buck i ever spent on my gun. Fit right on and was very tight. I had to put a screw driver through the delta ring into the hole for the gas block in the upper receiver to get it really tight. This also allowed me to have it lined up parallel. In the picture is shows this bolted on little piece behind the delta ring. That locks on to the upper receiver in the front so even if the delta ring is screwed on or is loose it doesn't move. It looks awesome and is the perfect length.

MY Only cons are-
It didn't come with directions and took me a while to get it just right.

The inner diameter is 1 and 1/8 a little bigger than that but still small enough that i couldn't make my suppressor look integrated. I just made a dense plastic suppressor and used a lathe to machine it down to the right size.

"I bought these rails about 2 months ago for my DMR setup. These rails are super lite compared to others of the same length. They use a common thread size , they fit my G&P upper as well as a friends KWA mod1 aeg.. These also fitted a real ar15 upper . Theses rails are supper solid imo. Now to the pro and cons

-light weight
-really easy to install even if you know nothing
-great price

-not made to be use for front wired guns (Can be done but really hard)
-Rails are sharp (I do suggest rail covers)
