Q
Z, member, from KY, United States, asked on October 27, 2019

So is this barrel not 16 inches without the muzzle device being welded on? I don't want to have to pin and weld the muzzle device.

Expert Answer
A
Answered by Armando R., Gear Expert, from IL, United States, on December 02, 2019

The models listed as having a 16" barrel will be a full 16" regardless of the muzzle device. If it lists that the barrel is under 16" then that is the true barrel length.

Theo, guest, from CA, United States, asked on September 17, 2019

Just this come with the gas block tuned and ready to go? Or does it need adjustment. Thanks

Expert Answer
A
Answered by Armando R., Gear Expert, from IL, United States, on October 15, 2019

This has a standard low profile gas block that has not been "tuned" as tuning requires a complete rifle because you need to consider both buffer tube system and gas system.
