Strike Industries Collar Adjustable Gas Block for AR-15

Product Description

The Strike Industries Collar Adjustable Gas Block is a clamp-on adjustable gas block for the AR-15 with 6 settings. It gives you a way to change how much gas your rifle uses to cycle, without swapping parts.

The collar is what you turn to pick a setting. There are 6 to choose from, so you can step through them one at a time while you tune the rifle. The block mounts by clamping on, and it fits any .75in gas block journal. Check your barrel’s journal size before you order.

Who it suits

This part is for AR-15 builders who are putting a rifle together from parts, and for owners who want to change the gas setup on a rifle they already have. If you are working with a barrel that has a .75in journal, this block is built to go on it.

It pairs with the usual parts of an AR-15 gas system. That means a barrel with a .75in journal, a gas tube that matches your barrel length, and a handguard with room around the block. Muzzle devices and other front-end parts are chosen separately, so plan the whole setup before you start. The manufacturer part number is SI-AR-CAGB if you need to match it to a parts list or build sheet.
