Good tube at good price - ODIN Works Gas Tubes

Gas tubes usually pretty much the same but the finish - Stainless/ Melonite /blackor shiny and the end that the bolt carrier group receives with a flared end! I have only had one (not this one) that was cut wrong- was too long and I had to trim it drove me crazy! Make sure you get the right length and that the handguard covers it completely! choices/ sizes are Pistol, Carbine, Mid, Rifle, and they do make a magnum one which should match your barrel specs as far as length! I blow air through it when I get it installed to make sure gas block lines up with port in barrel and that tube has no debris or obstructions- it doesnt take much to clog it!only other thing to get right is with the barrel nut and holes/grooves in it so that gas tube is straight and lines up with gas block. Optics Planet has many choices at good prices and good shipping speed!
