PTR 9LT SBR CS – 9X19MM – SBR WITH CS1 COLLAPSIBLE STOCK

The PTR 9LT SBR CS is a semi-automatic 9×19mm short-barreled rifle sold with a PTR CS1 collapsible stock installed at the point of sale. It utilizes PTR’s proven roller-delayed operating system and is host-ready for use with NFA-registered auto sear packs where legally applicable.

This configuration exists to provide a long-barrel MP5-pattern SBR optimized for improved ballistic performance while retaining compact handling and adjustability. The 12.5″ nitride heat-treated barrel supports suppressor compatibility, while the extended M-LOK® aluminum handguard increases available mounting space for optics and accessories. A tungsten dead-blow weighted, full-auto profile bolt carrier supports consistent cycling and long-term durability.

Within the PTR lineup, the 9LT SBR CS occupies the long-barrel SBR segment, combining extended barrel performance with collapsible stock functionality for professional, training, and suppressed-use applications.
