Geissele low-profile super gas block nitride coated 05-807n - Geissele Super Gas Block Black Nitride Coated

The Geissele Super Gas Block Nitride Coated part number 05-807N is the newest version of their super gas blocks, is the only gas block Geissele sells directly. This LPGB has a lower profile than their 1st generation super gas blocks. This super low profile gas block will fit under all Geissele SMR rails. I purchased for a custom FNH upper build and fits snuggly under a 5.56 Cold Hammer Forged Mid-Length Barrel - Hybrid Fluted - 16" I prefer the black nitride coated version as it is more durable and matches black barrels better. This is a high quality Geissele low profile gas block and comes with detailed instructions, set screws, and pinning roll pin. The bore of the SGB is machined to closely fit around .750” diameter mounting bosses found on most M4 Carbines and AR-15 rifles. Highly recommend!
