I want to switch out my pinned stock with a magpul ctr milspec . The buffer tube is milspec, and I will be pinning the new stock.

 

Anyway do I need to change buffer tube. Someone told me I do. That don't make sense if if already.milspec

No. you shouldn't have to change the tube.

How long is the receiver extension (tube)? Can you feel the end through the rear with your finger?

Yes, I can feel it. It's pretty much a 3/4" from end

 

You do not have a mil-spec extension. If you want the stock pinned at a shorter length than that post-ban extension allows, then you will need to replace it with a CAR extension. There are two available. One is mil-spec and the other is commercial. Get the one that will match your new stock.

thast funny, Stag Arms says on their website that all their guns come with milspec

Milspec when speaking of a buffer tube usually refers to diameter. So if you wanted a new plastic bit, you'd get mil spec rather than civilian. You are just never going to make it short.

Never said I wanted to make it short, Im leaving it the same length. I found this one, and it says it will fit milspec or commercial
