The interchangeable front system means in essence that you can, for example, have a Stalon XS108 and then get an additional Front 149. Suddenly you have two models; XS108 and XS149. The same applies, of course, if you get an extra rear part. This creates endless possibilities if used correctly.
The modular system also means that all accessories are available to optimize the silencer according to preference. Accessories for the X series fit all models in the series, such as sights, accessory mounts, and neoprene covers.
