Does anyone know what the M17a2 stock barrel bore size is? Milsig website says they made the bore smaller but they don’t say what size.

I don't know, but message Doug Brown with the question (Milsig tech of legendary status) - and yes... I looked at that picture and noticed exactly the same thing.

I didn’t get an answer from Doug but I believe the stock bore is .686 in case anyone was wondering.


Edit: No one wants to confirm from Milsig and apparently there’s no specific bore and they can vary from barrel to barrel.

So I took a digital caliper to my own and its turns out it’s .6910
