Q
J, guest, from IN, United States, asked on April 17, 2018

Dose this item fit on a 5.56/.223 barrel?

Expert Answer
A
Answered by Jonathan D., Gear Expert, from IL, United States, on June 26, 2018

Yes, however you must match the barrel's gas journal diameter. Most pencil barrels have a .625 diameter and most other non-bull/heavy barrels feature a .750 diameter. You will need to verify or measure the gas block diameter of your specific barrel and match it to the appropriate diameter.

Will this work with a Midwest industry 15” combat handguard ..inside diameter of 1.3

Manufacturer Answer
A

Yes, the .750" diameter gas block is only 1.21" at it's tallest point so either diameter gas block should fit under the Midwest Industry Combat Handguards.
