RCM HK SP5K Spec Suppressed Bolt Group- Full Auto
The RCM SP5K Suppressed bolt group is expertly engineered for operating in full auto while suppressed. Although designed as a full-auto bolt group, it also functions perfectly in semi-auto receivers. This makes it the ultimate choice for enthusiasts desiring reliable cycling without swapping locking pieces.
This drop-in bolt group is specifically crafted for SP5K's but fits MP5K clones without the rear full-auto carrier block.
***Always check bolt gap when swapping locking pieces. When exchanging a complete bolt group, confirm the BCG bolt gap is in spec. If necessary, exchange rollers to achieve the appropriate bolt gap.
Compatible With:
HK SP5K/MP5K
PTR 9KT
In spec clones and custom builds.
