I have 2 BCA 7.62 Side Chargers … the SPIKES BOLT fits my 7.5 perfect. However doesn’t fit the the 16” at all won’t close and open. Had to smash it in and bang with hammer to get out. I put a DIFFERENT spikes bolt (I bought 2) and it didn’t fit it either. Both SPIKES BOLTS fit the 7.5 tho. I believe BCA quality control is to blame. If it doesn’t fit just call them and send it back.
If the carrier in the Bear Creek takes an AR15 dimension Bolt, yes.
