I am honestly torn between which one is better, buffer tube vs folding stock. But overall I may actually still prefer a buffer tube over folding stocks.
I have shot 556 from the following platforms, G36, Tar-21, AR-15, Type-97 (556 version of QBZ95), and AR-180.
All of them have pretty low felt recoil, but I feel like AR-15 has even a bit less felt recoil compared to the others (it's super soft shooting), and it is the only one that has a buffer tube.
I have filmed slow motions of me shooting a G36 (18 inch barrel form a default G36E set up) and AR-15 (16 inch barrel, M/P Sport II, not-modified) , and roughly compared the barrel rise. AR-15's barrel rise when shot is a bit lower than G36, and its felt recoil is also a bit less.
Now I am not 100% certain, but from my experience, I feel like a AR-15 style buffer tube really does make felt recoil a lot better. (However, I want to clarify that it's been a while since I've shot my AR-15 because it is banned in Canada
so my memory may play tricks on me)
That being said, so if it were up to me to design a rifle for PLA soldiers, I'd pick a a buffer tube over a folding stock based on my experience because I believe the advantages buffer tubes offer significantly outweighs the advantages offered by a folding stock.
Anyone else agrees with me? Do you feel like AR-15's are a bit softer than other 556 rifles? If is, do you think it is because of the buffer tube design or because of other things?
