I got this for my Echo 1 Platinum RIS M4 to cover the tight bore barrel that I installed. It has a great finish to it and the black color matches well the the gun! I had no problems with installing this, just pop in and you are all set. Overall very satisfied with the purchase.
Included flash hider
Hides my inner barrel
Price is alittle steep but good quality
other than that, pretty happy with it.
I got this because I wanted to increase the inner barrel length of my gun. Knowing that it was QD was a pretty cool option as well as the flash hider it comes with. The trades look sick and come up at a 90 degree angle (not like the other guy's). It is a bit snug tho and I had to use a wrench to get it on all the way. Other than that this was an excellent purchase.
Included flash hider
Lets me increase my inner barrel
Paint scratches easily.
Other than that, this was a solid purchase from AirsoftGi
