Probably not, Tapco seems to be focusing on more Paramilitary stuff these days for the AR, AK, FAL, M1A, etc.
I've talked to them, or should I say tried to talk to them, about my SKS related inventions and they don't even seem interested in any of that. I have a feeling they are at the point of not wanting to put time into anything with a smaller or limited market and, even though there are millions of MNs. The percentage of owners wanting to modify a Mosin is probably less than 1% of the available MNs in the US. When you consider the long standing ATI and the new Promag along with Boyd's and other wood stock LLCs, I doubt you will see Tapco jump in.
