I have a M&P Sport

grubbylabs · February 17, 2013, 01:44 AM

I am looking to get a Mag Pull collapsible stock and I need to know if I have a commercial or mil speck tube diameter. How do I find out what I have?

Looks like I found it. It looks like it is commercial.

S&W uses a milspec RE on the more expensive models and I'd expect the Sport to also be milspec. Are the threads at the castle nut raised? That would indicate milspec.

Most of them are commercial.

Great gun, isn't it?

Bushamster, yes. S&W, no.

OP, maybe you'd better measure to be sure. I'd expect S&W to use a milspec receiver extension. It wouldn't make sense to change midstream to commercial just for their Sport model.

S&W uses mil-spec buffer tubes on the M&P line.

I have a Sport, anyone need me to measure something?

Mil spec...The Moe stock fits nice and snug too compared to stock.
