your 14.5 the difference between the mid length and carbine length as in how soft yours shoots is that much again with a 16" barrel in a carbine gas layout. its the opposite of what your experiencing.

if a barrel maker goes out of the way to port a barrel correctly for a 16" and carbine length it will work well. but that is almost never the case. you can alos get around the over gassing with an adjustable gas block.
This is true and spikes is one that I ran into with over gasing a 16" carbine . I believe they do this to make them more reliable with cheap steel , under powered ammo . Its not a bad thing but your right it does over work components . I mitigated the problem with a 4.2 oz buffer which I believe most of their complete rifles come with a H2 buffer to eliminate that issue

they do it cuz its cheaper.

the weight of the buffer doesnt offset the gas beating on the bolt carrrier components. the gas goes into the key at higher pressure and slams the carrier open harder which can hurt the bolt lugs extractor and key more than needed.

the DI system is STILL a piston design but the bolt acts as the piston.

The Dissy is just a 16" carbine or mid length gas system with the front sight that has no gas function other than to get teh longer sight radius . Its all for looks . If thats what you like get it . Im building a 5.45 dissy / carbine setup right now.

yes. they arent reliable with lighter loads cheaper ammo etc. can be some issues.

a dissipator is a 18" barrel with a rifle length gas system. works so-so. its why you dont see a lot of em.

if you want the look do a 16" mid length with lo-pro gas block and rifle length free float. the vltor casv system looks pretty hot in that config.

Check out the new EMR rail by ALG (Geissele). It's super light and affordable.
