Description


The Milsig T17 is the newest evolution in magfed realism. Designed as a true 1:1 scale replica of the M4, the T17 combines the precision of shaped projectile feeding, a patented mechanical full-auto system, and lightweight maneuverability—making it a go-to choice for milsim enthusiasts and tactical players alike.

At its core is the Mini D.E.R.P. (Dynamic Exo Retention Platform)—a compact mechanical unit based on the proven HeatCore, fully removable and serviceable outside the marker. Paired with the F.B.U. (Flexi Breech Unit), the T17 adapts effortlessly to both roundball and shaped rounds with exceptional consistency.
