tbrice23 : I am interested in doing this can you give me the exact product number for that tubing and also tell me what tools are needed or any special tools needed ?I make my own from carbon fiber tube from Dragon Plate (dragonplate.com) I buy a 24" long pipe, use what I want for the guard and use some of the rest for reinforcement for sling studs/ bipod adapter . I like low pro adjustable gas blocks, measure your barrel nut and order that Inside Diameter tube. I use Devcon 10110 to secure it to the barrel nut but I suppose you could use screws or fasteners. I like it clean and smooth without fasteners.
