PXT AR Barrels
PROOF Research PXT carbon fiber barrel blanks combine next-generation rifling technology with the lightweight performance and precision that have defined PROOF barrels for years. PXT – PROOF Exponential Twist – is a complete rethinking of conventional rifling geometry and twist progression, engineered to reduce engraving force, minimize throat erosion, and create a smoother transition as the projectile engages the rifling.
By dramatically reducing rifling lead angle and smoothing projectile engagement into the bore, PXT technology helps reduce wear, improve consistency, and create less felt torque during firing for improved recoil control and the ability to stay on target more effectively.
In controlled testing, PXT barrels have demonstrated significant increases in barrel life while maintaining the accuracy standards expected from a PROOF barrel. These AR barrels arrive fully chambered and ready for installation, making them an easy upgrade for shooters looking to build or refine a high-performance rifle system.
Available in both PROOF carbon fiber and traditional steel configurations, PXT AR barrels deliver lightweight handling, precision performance, and next-generation barrel technology across a wide range of modern gas gun applications.

As with any business where you are considering sending money for a product, you should do your due diligence in researching the company. With good reviews I decided to take the chance and purchase a Stacatto on a few payments. I received notifications of payments, all emails where always answered in a courteous manner and item was shipped immediately after receiving final payment. Pistol was perfect, added red dot and host plate was perfect, Vulcan porting was perfect, payments were perfect and communication was perfect. For those looking to own a Stacatto or other high end firearms, my purchase from Tag Firearms was absolutely the best experience and my ported P4 with its HMR HD is exactly what I was expecting. Thanks to all that was involved. Greg Thomas

I’ll preface this by saying I rarely give 5 star reviews because I always believe there’s room for improvement. This place is the exception.
Today was my first time visiting TAG and these folks truly know their stuff. Anything you want to know, they’ll take the time to explain. It was hands down the best customer service I’ve ever experienced.
They didn’t just sell me something, they took the time to educate me, answer my questions, and make me feel like a valued customer.
This was my first visit, but it definitely won’t be my last. These folks will be my #1 stop from now on.

Ordered a suppressor cover and it was shipped via their free shipping option, USPS Ground Advantage. It showed delivered but never was. Their customer service was responsive and helpful at first, but I never got a response to my last email. While I understand that TAG isn't the one that lost my package, I'm still out a good chunk of dough. If you place an order, upgrade your shipping so you don't get stuck with ground advantage.

At the time of this review, I will be the 104th 5-Star review! I mean, c’mon, how often do you ever see a business with such a rock solid reputation like that? But im here to tell you guys, that its for real! James and Chris are down to earth, personable, intelligent, and professional all at the same time. I purchased a Staccato P from them, and they made the entire process super easy, and just had a great experience. Im already making a 2nd purchase! They definitely gained a loyal customer, and I will no doubt be using them for my future gun builds.

I’ve dealt with these guys for only about three months, but I can attest to the fact that this is the hardest working crew in the business, client always comes first, shipping is immediate and they will bend backwards to assist customers… also it is amazing to have a company take such pride in what they sell, this is truly a “white glove”, premier dealer!

I’ve been a customer since October of last year and will continue to be, the level of service is top tier! James and Chris have been absolutely amazing and I truly believe they will top any other firearms dealers in the country, I personally have vowed my allegiance to them as my number 1 firearm supplier and if you knew me that’s saying a lot as i am very picky! All I can say is don’t hesitate and check them out!

My experience with TAG Firearms has been great. The customer service is Top Notch and has been On Point every time. They have been able to supply all the hard to find Q Parts and Firearms. Been dealing with Chris directly and he has been very knowledgeable, gives no rude attitude, provides fast response, and provide tracking with fast delivery. I am a repeat customer and highly recommend TAG Firearms. Keep it going TAG Firearms.

Chris at Tag Firearms has been amazing to work with. Bought a Q Honey Badger and Trash Panda through him for a great price, and he couldn't have made the process easier. I have over 20 stamps from more than a dozen dealers and I've never encountered any stores as professional, responsive, and helpful as his. He's been available 24/7 for any and all questions I've had, whether through text/phone/email or even IG, and is super knowledgable about every product they sell (believe me I asked a lot of questions). Honestly can't say enough good things about this shop, already planning my next purchases through them. Hit him up for your NFA goods, you won't regret it!!
