CYMA Lite Free Float M-LOK Rail System for M4/M16 Series Airsoft AEG Rifles (Size: 9.75" / Black)

"This is a solid hand guard looks great feels great on the hand and just in case you were wondering the internal diameter of the front end of the hand guard is 36mm or in freedom units 1.4 inches

"Got the 9.75” to upgrade my polymer upper on a G&G CM Raider. Paired along with a 5KU 11.5” outer barrel. It took some adjusting of the hop up spring but other than that it was a perfect fit. It looks soooo good and it’s a reasonable price.

"Hit myself with it and still love it :p

"oh my word. I wish my experience was half as good as the previous ones.

this is the worst designed rail I've ever seen. the barrel nut is crooked, none of the holes line up, and it took quite a bit of finagling to fit it on my cyma upper.

save your money for a better quality rail system.
