Hi guys,

 

I've decided to replace my A5 style stock (pinned) on my Windham AR but since I'm a noob when it comes to AR's I was hoping someone could point me in the right direction.

I was initially looking to get an ACE skeleton stock kit, but changed my mind and decided to get a M.A.G.S. EFX A1 kit (Stock and buffer assembly) that is sold by Stag Arms. My concern is regarding the buffer tube connection and whether or not the new kit's tube would fit my WW lower. The WW AR's are apparently manufactured with commercial spec and not mil spec buffer tubes. I can't seem to find whether the EFX kit comes with a mil spec or commercial spec tube. If it happens to have a mil spec tube, would it still thread into the lower that was threaded for a com. spec tube? Anything else I may have overlooked for proper fitment?

Thanks for any help you can offer.

The threads are the same on Mil-spec and commercial tubes.

But obviously rifle and carbine tubes require different springs and buffers.

Interesting article.

U can thank Google for me finding that. Personally I wouldn't use a commercial stock on my ar. My ak on the other hand it doesn't matter

Thanks for your help guys, especially the article you posted cguiro. From what I've gleaned from the article and other searches on the web, it appears that I shouldn't have any problems with either (mil spec or commercial) tube threading into my AR lower. Since the tube, buffer, and spring are included as a kit with the new stock, it should be good to go.

Thanks again, I appreciate your help.
