"3/5 star rating for a very specific reason.

I bought this for my SCAR L too add 4.5 inches of barrel length. It is two pieces and as one it is a crooked, useless piece of metal. So I decided to put one half on my SCAR and the other on my AK 47. The pieces individually seem to be straight. Since I had to use half and half, this gets half of 5 stars.

"Works and looks good. It's actually two pieces. No complaints.

"I bought this to extend my inner barrel on my JG G36C. If you don't want a suppressor look, or if a suppressor won't work for you (in the case of a G36C it prevents you from removing the barrel), then this a great option. I then added a flash hider for looks, as well as extension. This allowed me to upgrade from a 230mm barrel to a 363 barrel, and I still have room left over. I think the aethstetics of a suppressor are better, but if you can't, this is a great option.
