The hand guard is very smooth, extremely impressed with the machining. Parts installed easier than expected, and is solid. Gas block works, no issues.
Long gas blocks are hard to find. This one is made well and I like that it has 3 set screws for extra secure mounting. The only improvement would be a nitride finish, but that's just splitting hairs. If you need to cover FSB scars this is the perfect choice.
Great price easy install very satisfied with product
