The SB Tactical SBT522 solves the brace problem for rimfire MP5 shooters by engineering an endplate specifically for the HK/Umarex .22LR platform’s unique dimensions. This brace works well for plinking and training with affordable .22LR ammunition, backyard shooting where you want MP5 ergonomics, and building a lightweight trainer that mimics your centerfire setup. What sets the SBT522 apart is the purpose-built design for .22LR receivers – it integrates side-folding capability and QD sling mounting while maintaining the proper fit for rimfire MP5 models that don’t share exact dimensions with 9mm versions.
