For sale is a Faxon 11.5" Gunner 5.56 4150 CMV MPI nitrided barrel with mid-length gas and 1/8 twist, and a matching SLR Sentry 6 click-adjustable gas block. These two are a perfect pair. The 11.5" Gunner is purposefully designed with suppressed SBRs in mind -- the combination of mid gas and an adjustable gas block makes for a very smooth-shooting combination. This barrel has a round count of approximately 1000 -- just barely broken in for a nitrided CMV barrel! It shoots great, and has fired several 1 MOA or better groups with hand loads and an Aimpoint. The gas block looks and works like new. I'm asking $200 OBO for both items. A gas tube is included as well. Will ship for $10. Separately, I'd want $125 for the barrel and $85 for the gas block, plus shipping. PM me here, email henschman@hotmail.com, or text four oh five, six three three, five one six four.
