The PRO2A 22" 6.8 SPC II Rifle Length Non-Reciprocating Side Charging Kit eliminates the complex engineering guesswork of building a custom modern sporting rifle from scratch. Traditional rear-charging configurations create awkward physical manipulation clearings when running large long-range scopes or thermal hunting gear. By migrating mechanical operation to a sleek left-side charger and bundling it with its specifically headspaced side-charging bolt engine, you can cycle the system smoothly without disrupting your cheek weld or target focus. Paired natively with a complete mil-spec lower components control kit and stock assembly, this master setup lets you build a highly robust rifle on any standard stripped lower receiver while keeping your sourcing workflow highly efficient.
