Q
Rob, member, from NJ, United States, asked on January 11, 2022

Will it screw onto the barrel of my Radical firearms 16" 300 blackout AR upper and how much does it add to the barrel length?

A
Answered by Dev, guest, from TX, United States, on March 29, 2023

No. This is used to MAKE an AR barrel. You attach it and then drill the gas port. Also this is a product for large frame ARs, not small frames.

Q
Robert, guest, from UT, United States, asked on February 15, 2021

Will this extension work with the 6.5 mm PRC Cartridge.

A
Answered by DevL, member, from TX, United States, on April 27, 2023

Keep in mind that 6.5 PRC is longer than 6.5 Creedmoor and the round is too long to fit into a SR25/LR308 style magazine. You would need a special upper, lower, magazine, and a bolt that was based on the LR308 bolt and AR10 type carrier system for this to work. You can't just buy this extension and a .264" blank and expect to send it to a smith and end up with a functional large frame AR in 6.5 PRC. The 6.5 Creedmoor and .308 use a .407" bolt face. The 6.5 PRC uses a much larger .532" bolt face. A large frame bolt machined to fit that large of a case head would have a razor thin support around the bolt head. Kind of like how a 6.5 Grendel bolt looks. So I'm going with 99% NO as my answer.

Will this fit a magnum AR10 barrel like a 300WSM or 6.8 Western?
