Heckler and Koch MP5 22 LR Features The Heckler and Koch MP5 22 LR is built around a 16.1 threaded barrel with 1/2x28 direct thread that keeps the platform suppressor-ready for hearing-safe rimfire use wrapped in an authentic barrel shroud and HK-style handguard that faithfully replicate the MP5 s iconic profile. The HK charging system and HK slap-able design deliver the same manual of arms as the full-size MP5 giving shooters a cost-effective training and range platform that builds genuine MP5 handling proficiency. The HK drum rear sight and HK front sight provide a classic field-proven iron sight picture that MP5 enthusiasts will immediately recognize. The fixed stock paddle and button MP5 magazine release and single stage trigger give this 22 LR MP5 rimfire rifle the authentic controls and ergonomics that define the MP5 platform in a lightweight affordable format. The blowback action cycles reliably through a wide range of 22 LR loads delivering consistent performance through extended range sessions. One included 25-round magazine completes a fully configured authentically styled rimfire package.
