Im looking to build a "scout" , "tanker" , "bush" rifle. Im planning to utilize a Smith Enterprise gas lock with dovetail for USGI type front sight. I was planning to use an LRB (Criterion) 18" barrel.
In looking at the description of the SEI gas lock/front sight, it mentions using it with 18-1/2" barrels. Will it work with the 18" barrel from LRB??
Also, regarding non USGI gas cylinders, would you prefer LRB or SEI? thanks
