    There are other factors that go into it as well. I wouldn't just assume because my set up won't cycle Tula, yours won't. Just try it out and see. I guarantee you will cycle better quality ammo so it's not like you will have a rifle that doesn't cycle anything. Also, you gotta figure out, how often do you shoot Tula or PMC Bronze. I never do with my BCM middy so I don't care that it doesn't cycle it. If I did then I'd probably get the lighter buffer.

    You are gonna get this with the A5 fellas as you may with any other RE setup. Some will cycle ammo with just a primer for propulsion (hyperbole) with the A5 system. Others will not. Different gas lengths, ammo, buffer weights, port sizes, springs, and even bolt carriers can make a difference....again...as in any other setup.

    If you are like me you want your rifle to run with the weakest commonly available ammo out there. PMC Bronze is not exactly consistent on the chronograph but it is consistently weak. Have seen it go as low as 2650 fps out of a 16" barrel. My rifles with A5H3s will run it filthy dirty on that stuff and that's with 14.5 middy barrels. But I am not everyone obviously as some have different results. Buy the A5 system and if you have problems (and want to stick with the A5) with it running your specific ammo chosen then start playing with buffer weights. They will all interchange with standard carbine buffer weights except for the one closet to the front. There isn't a universally perfect setup for every carbine but the A5 is by far the closest.

    You mean the weights right? Some people might read your post and think they can use a standard buffer with a A5 spring and extension.... (yes, people are that stupid)

    I suggest that for those who are unsure about buffers and ammo and the little variables you should read my posts when I was doing various testing. From my experience a properly sized carbine gas system will function with the -3 when using M193/M855 ammo. There is more to the A5 than just the weight. The fact that it uses a rifle spring is also a plus.

    In my opinion, the rifle spring is the biggest plus.

    I would hope most of the members here can understand why a longer spring with less resistance is better for the system than a shorter spring with more resistance.

    Yeah Will, that's what I was saying in my last post about the rifle action spring and consistency.

    One of these days I really need to try that buffer in the Colt.

    The rifle action system properly weighted and sprung has many advantages over the carbine action system that is properly weighted and sprung. Reliability and durability are first on the list, possible reduced felt recoil and reduced brass stretch are farther down the line. The A5 system uses the rifle action system in a adjustable package. Depending on the application, the A5 can be useful. It really depends on the use of the rifle in question?

    For those of you with the A5 tubes, on the inside, is there something that looks like an extrusion line? It is hard to explain without a picture, but on two tubes I have gotten over the past year there have been "lines" on the inside that can be felt with a finger.

    Anyone else see what I'm talking about?

    Just an example. I have a lower with a -3 buffer and green Sprinco spring. I have tried 3 different uppers on that lower and all of them cycled and functioned correctly. 20" rifle, 16" carbine, 11.5/12.5" SBR, and .300 BO.
