Looked all over for the best price. Found this place and the block came with the gas tube also. It was as cheap as anywhere else. Shipping was great. Shipping price was very fair. Note: This will fit under a dpms lrt sass 308 handguard but it's a close fit, real close. So some of the other ultra slim handguards should fit as long as they are 1.38 ID and for a 308.
