Will this fit an armalite ar10?

This will fit on the Armalite receiver, but there's more details we need to give you an accurate answer whether you have an Armalite AR-10 A or B Series AR-10 as the bolt carrier is different and requires different length buffer tubes. Send us an email at techsales@opticsplanet.com and we can help you identify what you have and get you set up with the correct extension.

Poor internals by Straws, Verified Owner, August 2, 2019
Product was shipped to me spring of 2018. Thanks to OPTICS PLANET it arrived quickly and on time. However Guntec left the inside of the tube ribbed with an improper buffer spring and it caused my AR-10 to have unreliable cycling. Apologies for the la...
