    Okay, okay I'll give in...just don't call me old. :rolleyes:

    My corrected eyesight is 20/20 and prescription hasn't changed in almost 30 years, BTW.

    peace

    <--- old :)

    you can still have 20/20 vision but difficulty focusing up close. as i'm sure you know, that's why so many people over 40 (myself included) have reading glasses but not prescription glasses.

    No.

    H buffers were developed to enhance reliability (by lowering cyclic rate) of M4 carbines.


    Depending on the outcome of the currently underway Individual Carbine selection process, the successor to the M4 will be piston operated.

    Well I'm actually near-sighted and can see the front post clearly without glasses. It's the target I need help seeing. Dang thing keeps moving around on me...LOL

    Taliv is on the right track. The process of firing a cartridge is analogous to a constant mass deflagration constrained to the rifle barrel. Which is slightly similar to a reacting shock tube type wind tunnel.

    Thermodynamics holds that if a gas is held at constant temperature and it's volume is increased, its pressure must decrease. For our purposes, we can assume that the reacting volume inside the barrel is at constant temperature. Thermodynamics has held up for a few hundred years, but try to disprove it if you wish.

    Thus, basic physics says that P_carbine gas port>P_midlength gas port>P_rifle gas port.

    Practical, hands-on applications that are proven useful, reliable, repeatable, are what work for me. The carbine has worked in practice in the "civilian" market for decades. Practice, not theory. If the mid-length gas system proves to be significantly superior, I'll recant.

    BTW, my son-in-law just returned from his fourth deployment with the USMC, two in Iraq and two in Afghanistan. His unit lost 37 souls in Fallujah. I asked him how they maintain their M4s. He said they clean them regularly and leave them bone-dry. I'll bet that runs counter to someone's "conventional wisdom" on this board.

    If you feel the need to upgrade to newer design, please be my guest.

    It runs counter to science, wisdom, and what the most experienced people teach.

    Not excuses, facts. Don't like ARs much do you! :D

    We usually didn't lube M16s when I was in the Army either, but for us it was simply because it made them appear "cleaner" during inspections.
