Home Forums Hunting & Shooting AR and Tactical Rifles Gas piston vs. gas impingement

piston runs cleaner and cooler

impingement works fine for 99% of us and is cheaper. I own/have owned 223, 260, 308, and 300 SAUM ARs. All were impingement, never ever malfuctioned or were cleaned very often. None were full auto, burst mode, or ripped off 20-100 rounds as fast as I could pull the trigger.

The AK 47 uses a gas tube system. What is the most reliable military semi-auto battle rifle ?

Gas tube is "tactical cool" so it must be better, but the tubes need to be cleaned too.

With the exception of the cabon fiber 223s, (impingement) they are all too heavy, good for killing people and questionable (compared to alternatives) as a hunting rifle.

4.5 pound 223 with lexan magazine, w/o scope, light & laser. Shoots minute of raghead out to 300. That's all it is for.
