I bought this for my Classic Army LWRC sportline shorty. Way better than the stock barrel, heavier material with guides so the barrel will not strip out. I love it, a bit longer than what the gun came with, but a perfect match for my gun. Overall great barrel and would completely recommend it, all the issues I encountered were not BIG problems at all.
Original iron site fit perfectly(with matching guides).
Perfect if you want a shorter barrel.
Color match is awesome
Universal fit for flash or muzzle hiders(Also purchased a JG flash hider).
Like any part you can buy for a universal gun, I had to get a small file to make the barrel attachment fit the upper receiver. Once filed down it fits snug.
A bit longer than I thought(not by much) so I had to purchase a little longer inner barrel.
Since it is a thicker barrel my original battery pack will not fit without taking time to place everything just right.
