VFC 20" Sniper Conversion Kit for HK417 Series Airsoft AEG Rifles

"To start off, the build quality of this rail is superior. Along with the barrel. The installation of this kit is also super easy to do! The only negative I had was how heavy the barrel extension was.

"The quality of the build is top notch, the rail slides on and is fixed very tightly around the gas block and barrel of the rifle, no wobble whatsoever. The flip up sights are excellent, only complaint is that the rear sight doesn't move up or down. The biggest problem is that the outer barrel extension alone is like a pound and makes the rifle INCREDIBLY heavy.

Pros: Metal is great quality
No wobble whatsoever
Easy to install
Sights are unique, no wiggle room

Cons: Outer barrel is way too heavy
Rear sight doesn't adjust vertically
