Thank you everyone for your help. I truly appreciate it and the link to the resources.

Found a pic of what its supposed to look like

F if i know

There are a ton of bolt catch threads. Any suggestions as to what key word could I use?

I purchased a side charging BCA10 chambered in 6.5 creedmoor last february. The seller is an FFL and built the rifle from Bear Creek Arsenal parts, but forgot, lost or didn't receive the bolt catch. Instead of making a big deal and hassle, I told him no worries and i'd just order a bolt catch and install it myself. I finally got a chance to install it and it doesn't fit, and based on what I've seen, I don't know that anything would fit other than a part direct from BCA. The builder and I have contacted them and don't seem to be a lot of help. They're requiring a receipt and won't sell me a bolt catch outright due to "supply and liability issues." It's just a bolt catch, this doesn't seem like something to argue over. The lady at BCA I talked to yesterday said that it's a "DPMA GEN 1 DESIGN LOWER" but that doesn't stop BCA from customizing the part, does it? I mean, I just thought that primarily meant the curve of the grip. I've attached a picture of where the bolt catch should be. It looks like there should be some sort of additional nub on the bolt catch? Please help. Any suggestions or compatible aftermarket references appreciated
