Bolt catch out of spec?

[Badger89]

Is there any way to tell if you're bolt catch is out of spec? I'm having an issue with the bolt on my .22LR Upper locking back prematurely, before the magazine is empty. The manufacture of the adapter block I am using (Better-Mag S&W .22 Rimfire Magazine Adapter) reasoned that my bolt catch may be out of spec and causing the malfunction. I'm not going to re-hash the entire story here, but if you are interested you may read this thread.

The bolt catch (and the rest of the LPK) is from White Oak Armament, the lower is a Seekins SP15 forged lower, and I assembled it myself. As stated the adapter is the Better-Mag adapter from Redi-Mag. I'm just trying to figure out if there is any way to verify that my bolt catch is out of spec or not, before I call WOA and inquire about getting a replacement. I really want more to go on other than just saying, "Well, I'm having issues with another product and the manufacture of that product said yours may be bad." Please understand that I am not intending any disrespect toward EITHER of these manufactures, or implying fault. Both have been excellent to deal with in my past experience and have great customer service. That is why I'm trying to do as much homework on my own first before asking customer service to fix a problem I haven't even completely narrowed down yet.

A bit more background info: Both the lower and the CMMG .22LR upper are nearly new, both having a round count of 200. I have not yet mated this lower to a complete 5.56 upper, and I do not currently have an assembled 5.56 upper to try for any testing. Has anyone ever had this problem, or a similar problem, with either a .22LR upper and adapter, or a standard 5.56 upper? How did you fix it, and where you able to determine the cause? I understand that I could replace the entire adapter and the LPK for less than $100, but I'd rather not spend money on new parts when I don't even know definitively what's wrong.

Thanks.
