I've got a highly modded Colt 6450 that has issues with the BHO.
It is a late model 6450 that uses a standard 5.56 bolt catch and a little actuator device in the mag block. This actuator is a little stiff, which causes it to push down the empty mag follower 9 times out of 10. I am using factory Colt Metalform mags. There is plenty of bolt travel to lock the bolt back manually. I was wondering if I could easily convert to a long finger 9mm bolt catch and do away with the actuator in the mag block? |

The long finger 9mm bolt catch follows the KISS philosophy.
For a dedicated set-up, I would always run the 9mm bolt catch as it acts directly on the follower - no need to worry about the actuator getting dirty and binding up. For a quick swap set-up using a bottom load block, it is easiest to just leave the 5.56 bolt catch in and keep the block clean and the actuator loose, or use a Hahn quick swap std. top loader with a 5.56 bolt catch without LRBHO. (LRBHO is nice, but isn't really necessary) |

Quoted:
Does the actuator come out when the bolt catch is removed? Or is it pinned to the mag block? The actuator is part of the block - how it comes out depends on the block - I am not sure on the Colt's, but on the Hahn's, you can just take them apart and remove the actuator - it basically rides on 2 pins. Older Hahn blocks needed the actuator to keep the ejector in place, so folks with those blocks wanting to remove the actuator would need to somehow secure their ejector. I believe newer Hahn blocks have an ejector that is bolted to the block to better secure it and keep it from interfering with the actuator. As a last resort, you may have to file off the protrusion on the actuator and just leave it in place - then use a long finger 9mm catch over the top of it. |
