Hello guys, I was wondering what makes a stock able to have 6 positions?
Is it the buffer tube or the stock makes up the positions. Can you put a 4 position stock onto a 6 position tube and will it be able to have the 6 positions.

Forgive me for this dumb question but I dont know:(

The buffer tube has either 4 or 5 holes in the bottom for the locking pin of the stock to go into. Doesnt matter which stock you use

the receiver extension (tube) has holes for the stock.

You can put a collapsable stock on a 4-postion tube, 5-position tube, or 6-position tube. It will work on all of them.

The buffer tube

Ok thanks, thats what i figured. thats what every notch in the buffer tube is for huh. The stock basically just clicks into each position that is available. I wasnt sure but thanks for answering quickly. :)

On Mil-spec stocks the locking pin locks into the holes in the tube. There are 2, 4, 5 and 6 position tubes.

Commercial stocks have the locking pin in different positions, so one commercial stock may work on a 6 position tube, but another stock may only lock into 5 of the 6 positions. This is due to where on the stock they put the pin. IIRC UTG 4 position stock kits have stocks that can not lock on all 6 positions. I had a 4 position CAA and it worked on 6 position stocks.

In any case, the number of locking places in the tube is the number of positions the stock has.
