Rifle length gas system on 16" barrel

[KBScobravert]

Chris, here is a carbine barrel up top compared to a middy barrel. Both are 16".



They say the middy is the best and that true dissapators don't run.

True dissipators don't run because their is very little dwell time, which requires a larger volume of gas due to the shorter gas cycle. Thus, if something doesn't work, it's a very hard to tune system. Similar to a 10.5" carbine gas AR system. The 11.5" is MUCH smoother due to increased dwell time and a smaller gas port.

My new build. FN hammer forged 16" middy gas.
With an A2 standard rifle buttstock. I like this stock on this gun the most I think.




I never would have believed that the A2 is the shortest of the stocks after the adjustables are fully extended. The PRS on top is not out all the way either. Bottom rifle is Threefingerpete's upper.

I am building one like this saving for the barrel and have to decide on sights / muzzle device. I have one of those ALG triggers I am going to try in it.
