The TAC-41 is one of the most modular bolt-action platforms in airsoft — nearly every part on it can be swapped, upgraded, or fine-tuned. This guide breaks down every upgradeable system on the rifle and links directly to the parts we stock.
Outer Barrels
The outer barrel is both cosmetic and functional — fluted and twisted profiles shed weight while triangular profiles add rigidity. Available in 330mm, 420mm, and 510mm lengths depending on your chassis.

Hop-Up System
Hop-up tuning is where most of your accuracy gains come from. Swap the complete unit, or just fine-tune with a different bucking angle to match your barrel length and power setup.
