When you want to build an AR type pistol, you deserve the same great quality parts that are available to the guy who is building an AR carbine, it’s sort of a no-brainer. The problem is, the market isn’t built that way so you could end up wading through a bunch of manufacturer of the month dregs before you come across something that really does the job it’s supposed to do. Do you want performance that goes above and beyond? Let’s make this simple. If you want an AR pistol buffer tube that has evolved beyond basic function you want a Primary Weapons Systems Mod 2 Enhanced Pistol Buffer Tube Kit.

The PWS pistol buffer tube kit brings the same forward thinking design evolution and cares that other PWS products are designed with to the simple AR pistol buffer tube. When Primary Weapons Systems’ designers were done, the long neglected pistol buffer tube kit got a new breath of life. An impact extruded tube body of 6061 Aluminum with an extended carrier support lip holds everything steady and enhances the performance of your system. It accepts most cheek pieces and pistol supports and features the same lightening cuts to reduce weight while the fluted design lets debris fall away instead of hanging around to screw up the works.

Like their carbine buffer tube kit, the PWS pistol buffer tube kit includes their ratcheting castle nut and advanced end plate with QD attachment. Attach your buffer tube solidly without staking it and feel free to remove it without sweating bullets. If you like a sling wrap to add stability, the QD end plate allows for easy attachment of the sling that makes that secure hold possible yet allows you to get the sling out of the way if they’re not wanted.

Because It's Time. The PWS Pistol Buffer Tube Kit. Evolution is everything.
