Strength you can feel. Weight you barely notice. Precision that defines performance.
Matte black, rigid, and ready — engineered for those who demand more than plastic.

Unmatched Strength and Rigidity

Up to 38% Higher Tensile Strength – 69 MPa vs. 50 MPa for Nylon 12, giving parts more load-bearing capability.
Nearly 3× Stiffer – With a tensile modulus of 5.3 GPa (vs. 1.9 GPa), PA11 CF parts hold their shape under pressure and stress.
Over 65% Greater Flexural Strength – 110 MPa vs. 66 MPa for Nylon 12 means stronger parts that won’t bend or deform.

Superior Heat and Environmental Resistance

Designed for high-temperature applications where Nylon 12 softens or degrades.
Carbon fiber reinforcement improves thermal stability and lowers thermal expansion for precision even under heat.
Naturally resistant to moisture and UV exposure, ideal for rigorous outdoor use.

Professional Finish and Lightweight Design

Carbon fiber infusion produces a sleek matte black surface — functional and aesthetic right off the printer.
Delivers metal-like strength at a fraction of the weight, enabling lighter, more efficient assemblies.

Designed for High-Pressure HPA systems

Lightweight carbon fiber composite reduces load without sacrificing strength or rigidity.
Tested for durability across extreme temperature and humidity conditions to ensure reliable field performance.

Rigid Carbon Fiber Structure

Low expansion under heat preserves airseal integrity during rapid-fire or sustained full-auto use.
Machined precision surfaces ensure smooth magazine insertion and consistent alignment with feed paths.

Advanced Finishing

Custom Cerakote & Precision Coatings

Our in-house finishing delivers Cerakote and precision laser engraving with exceptional durability and style. Every surface is treated, coated, and inspected to ensure flawless performance and lasting quality.

    5 Stars to AW because that piece of the system works perfectly.
    5 Stars to TAPP’s customer service for responding very quickly and shipping me new parts at no extra charge!
    4 Stars overall because I did have some issues with my TAPP system parts. I will share my experience on the field with it

    I tested the mag at home before leaving my house with a few shots. It was operational when I hit the chrono. The site does not tell you, but the valve that it comes with will most likely increase your feet per second slightly. Possibly +20 FPS. During the first game it starts dry firing every other shot. I removed the magazine, and the feeding lip was already broken. It came with a spare, so I replaced it. After using it for several shots it started kind of spurting and losing all power after one or two shots. This did not make sense since it was full of gas. I tapped on the valve emergency latch (where the “firing pin” strikes the mag) to test the valve and it got stuck WIDE OPEN! Luckily no one got hurt. I had to buy the tool to remove the valve and oil to lube the O ring inside. I got the tool before I got the new parts from TAPP so I reworked the valve and re-installed it. I had the same issues, so I got a very crappy valve somehow right out of the box.

    The NEW valve that TAPP sent looked slightly different. The portion where the firing pin strikes is different. The inside parts look the same. I have oiled and installed this new valve and fired about 100 BBs through it perfectly. I am probably jumping the gun, but the issues seemed to be resolved, and it works as intended. Be prepared to learn to work on this unit. Eventually it will need maintenance anyway, just like your other gas magazines. The silver lining is that I will need these tools and oil eventually anyway. Overall, thank you! I am looking forward to the next game with my 400 BB’s!
