PSA PA10 Barrel Nut


For use in PSA PA10 and PTAC TAC10 upper assemblies.

The AR10 platform does not enjoy a common design between manufacturers, like the AR15.    As a result, there can and will be subtle differences in the parts kits of various manufacturers.  Some parts, like the fire control group, are shared with the AR15 platform to preserve the options for upgrading.  For best results, we recommend only using PSA PA10 parts with our uppers and lower receivers.  We do not recommend using other manufacturers parts in our products.

Excellent Barrel Nut for PA10/AR10/LR308
Purchased this Barrel Nut from PSA to work with a generic, low profile, DPMS pattern upper receiver. Worked perfectly.

Great barrel nut and coating
This barrel nut is built well and the threads are not sloppy. The environmental coating; I believe is nitride and is thick. I'm confident it will last for many years without corrosion. Could you get one cheaper elsewhere? Probably; but why??. PSA has all the other items that you need for your build, so just save yourself the extra shipping cost and monkeying around and wasting your time to save 5 bones and just buy it at PSA!!
