Zion Arms R15 Mod 1

This rifle comes equipped with a Deans connector, which is generally preferred over standard Tamiya connectors for better electrical efficiency and a more secure connection.

Yes, the R15 Mod 1 features a programmable electronic trigger unit. This allows you to customize your firing modes, including setting up burst fire options directly through the trigger system.

It is quite straightforward. The rifle includes a quick-change spring system, meaning you can access and swap the spring without needing to disassemble the entire gearbox, which is ideal if you need to adjust your FPS for different field limits.

The rifle features a 10-inch M-LOK handguard. This modular system allows you to directly attach M-LOK compatible accessories like grips, lights, or lasers, and you can also add Picatinny rail sections if you have legacy accessories.

Yes, it is equipped with a 6.03mm tight bore barrel. This tighter diameter helps improve air seal and consistency, which generally results in better range and accuracy compared to standard-bore barrels.

Given the muzzle velocity of 380-400 FPS, we recommend using .25g or .28g BBs. These weights provide the best balance of stability and range for this power level, helping you get the most out of the rotary hop-up system.
