Questions & Answers
What's the maximum handguard length recommended for this barrel? Expert Answer

That will depend on the muzzle device. In general you will want to stay shorter than 13.5" but if you have a blast shield or a linear compensator, you should be able to use a longer handguard up to 15".

5.56 barrel with integral 3 chamber brake. Which exactly is the pencil barrel and gunner barrel? The titles don’t match the feature list descriptions Manufacturer Answer

The barrel with MPN: 15A58M16NPQ-IMDB is the pencil profile barrel and the barrel with MPN: 15A58M16NGQ-IMDB is the Gunner profile. It does appear that the Optics Planet description lists "Gunner" for both, but the one with "P" in the part number is the Pencil profile.

Helpful Positive Review Great product by johndon762, July 22, 2021
I bought a lesser product that was slightly heavy AND noticeably less precise at 100 yds. Well finished, installs as expected, and performs very well despite very light weight. This is the gateway drug to Faxon barrels in general.
