I was kind of wondering why everyone believes the buffer, tube and spring are no longer required when the short stroke gas piston is implemented?
Removal of the recoil buffer spring to a forward position isn't a given, and most I've seen leave the recoil spring in the shoulder stock.
I guess if you were one of the 'Short Gun, Spray & Pray, Hollywood Wanna-Be' guys then a folding stock is OK...
Or even worse, one of the 'Machine Pistol' weenies
Personally, when I pick up a rifle I want it to have a full, solid shoulder stock, a long barrel, be hyper accurate since I only intend on firing one well placed round at a time,
Usually from 300 or more yards away.
Folding stocks, Lights, Lasers, Bayonets, Vertical Grips, or any other of that 'Mall Sniper' or 'Tacti-Cool' crap doesn't interest me.
That stuff is for cops that have displaced penis envy and pimple faced high school kids that play too many video games...
