The buffer tube screws in to the lower.the adjustable stocks are the ones with a nut holding them on, and there mil spec and commercial buffers tubes for those and the stocks only fit one not both.
I went with a fixed stock, cause I'm from mass and the few ar's I've shot I always pulled it all the way out Any way. I didn't need the tactical cool look. I wanna make it a light , and simple stupid Ar you know what I mean ....
Brownells have some good videos. I've used them so far.
I'm assuming the stock comes with the hard ware that screws it to the buffer tube.one screw in to the rear of the buffer.
Check back in a few days should be on my door step mid week.
I paid 108$ or was it 109$ for it shipped from midway to mass.
Model one sales dose not have a checkout etc etc so I went hunting for the same deal and found it on midway but I had to order the buffer stuff one by one.no package deal tho ..
Just read what length buffer you need with the stock. They have a shorter one you use a different buffer tube with. The full size one uses a2 parts...that what I got.
I'm very new to ar's so I can't really tell you if what makes a better buffer tube ,buffer etc etc. I just liked the stock for some thing light and simple etc. And the rest of the stuff was price mainly... i know i know you get what you paid for.
I kinda wished I went with a wood set tho
.
I'm a wood worker and build custom bass guitars so I might down the road carve a stock out of some crazy wood..
