Barrel Nut for shoulder-less barrels


Product Description

Barrel nuts are an often overlooked necessity of the home-shop rifle assembler.  We at PVA strive to produce the finest rifle barrels available anywhere on the market for every action.  Since a solid barrel needs a well made, true nut to lock it onto the receiver we decided it was time to make one.


Our barrel nuts do not require special tools or proprietary wrenches (that always seem to cost more than the barrel nut itself).  These nuts use any crescent wrench to tighten them up.   


We cover all the popular sizes of barrel tenon thread patterns for shooters that like to do their own gunsmithing and armorer's work at home.


1-1/16" pattern in 16, 18 and 20 tpi

1" pattern in 16 tpi

26mm x 1.5mm metric (Howa 1500 pattern)

27mm x 1.5mm metric (Sako TRG)

27mm x 2.0mm metric (Accuracy International)


The AI & Sako barrel nuts are specifically designed for customers that want to convert their aging AIAE rifles to an easy change barrel type using the American Rifle Company BarLoc system.  They can be used with or without the BarLoc and our match-winning replacement barrels!


Recommended installation torque is 45-60ftlbs.

Users MUST take care to be sure the barrel tenon threads are free of dirt and debris as well as being well lubricated prior to assembly.


We use and recommend any of the following thread lubricants for this product:


Anti-Sieze products either copper or nickel based.

Lubriplate 130-A grease (commonly known as M1A grease)


Others are avaiable and functional but we know these products to work well.

  1. Most convenient barrel nut made 5 Star Review

    Posted by on Jul 30th 2018

    No need for speciality wrenches. Just a 1.25" box end or large adjustable will do the trick. Holds tight and looks good as well. Not to mention, the PVA prefits are the most accurate prefits on the market, and equally accurate as any shouldered barrel. Buy with utmost confidence.
