Madbull Daniel Defense 4" Lite RIS Kit for Airsoft M4 / M16 Series (Color: Black)

"Fantastic little rail. Another quality Madbull product!
10/10

"This little rail is awesome! The quality of the parts is great, the machining is clean, and everything threads well. The inner barrel (although short) is clean, and from what I've noticed is very consistent, even at some distance. I initially installed this on my Krytac CRB and when I was trying to install it, I found that I had to grind down the little "gas tube" peg that holds the first part of the rail in place but once I did that The rest of the assembly went smoothly. Just be aware that the barrel might wobble a little bit, but that's nothing a little teflon tape wont solve in 5 minutes. I currently have it installed on a set of Calydon Arms receivers and it's as sturdy as ever.

Pros:
Solid rail assembly
Inner barrel is good quality
Looks great even for a short rail

Cons:
Might take a little bit of work to put together, but this shouldn't be hard for anyone with half a brain and a couple tools

"Threw on my combat machine. Looks great. Solid. Shoots great. With this and some krytac internals, what was an eye sore of a gun is now arguably one of my favorite pieces.
