Right To Bear 13.9" Pencil Profile Barrel 5.56 (Mid-Length)

This 5.56 chambered 13.9" Pencil Profile Barrel is machined from 4150 Chrome Moly Vanadium steel with a QPQ Corrosion Resistant Finish and QPQ coated M4 feed ramp extension.

Quench Polish Quench (QPQ) is a specialized type of nitrocarburizing case hardening that increases corrosion resistance. It is sometimes known by the brand name of Tufftride, Tenifer Black Nitride or Melonite. QPQ is a huge improvement over Chrome Lined barrels. Unlike chrome lining, where the chrome is built up on the surface, QPQ converts the surface without the risk of dimensional build up.

    Great quality barrel

    I was looking for a pencil barrel and tried another brand before purchasing the RTB. The other brand fit very loose in my Aero Precision upper, this was a concern. The RTB fits nice and snug. No issues at all with mounting. Pros: Great finish. Slim design. Cons: Only wish it was dimpled.

    RTB 13.9" Pencil Barrel

    I am no AR barrel expert by no means. However I will tell you what it I know. I swapped out my 16" barrel for the RTB 13.9" Pencil Barrel, The fit and finish were flawless as expected for an RTB barrel. after installing and P&W, I shot sub moa, with 3 shot strings @100yrds using off the shelf ammo. I am very happy with my purchase. I love how it balanced my AR, shifting the weight more to the rear, making it less nose heavy, more maneuverable. I just feels right, like it was meant to be. I do recommend this RTB 13.9" Pencil Barrel get it while you can you wont go wrong!
