Seller forgot to mention the fact that the gas block is essentially a paper weight with a partialy drilled hole in the wrong position. Had I known this, I would not have responded to his ad. Gas block and gas tube that were a "set" are incompatiable- Tube and gas block are the same diameter. Does not engage on gas block lip. he willingly gave a refund so I wont give him The Big Red One. Will NOT engage in any further business with this seller.
