ODIN Works has introduced two new versions of their adjustable gas block designed for barrels that have .875″ and .936″ diameter at the gas block mounting portion. The most common AR-15 gas block diameter is the .750″. However, some barrels with thick match profile or those with large bores have a larger diameter at the gas block portion and require enlarged gas blocks.

ODIN Works gas blocks are made of steel and feature a nitrided surface treatment. The adjustments are done by simply rotating the front adjustment screw which has 20 positions. The screw is fixed in each position via a ball detent. The adjustment screw and the detent spring are made of Inconel to better resist the high temperatures generated at the gas port.

The overall weights of these gas blocks are 2.45 oz. They come with an Allen wrench necessary to rotate the front adjustment screw. As you have noticed, these are low profile gas blocks which will fit inside of many free floated handguards. In case if you have a long handguard and the gas block gets positioned too deep inside the handguard, you’ll need to have a longer wrench which ODIN Works also sells on their website.

Right now the ODIN Works .875 and .936 adjustable gas blocks are listed on their website, but they are not available for purchase yet. These products have a “coming soon” status but the price point is already set at $89.
