http://www.cdnninvestments.com/ they still have a few in stock. $119.95 +$10 s/h for anyone who is buidling an AR... or will be in teh future. I bought one the other day. Colt M16 carriers and bolts are VERY hard to find at that price. SAW sells the same thing for $280..... and YES, M16 carriers are legal in semi-auto AR's. tehy are also more reliable than the standard AR carriers or the stupid colt half moon carriers.
