I got to thinking about buffer springs when I was setting up my Ares Defense MCR. I used the buffer spring that came with the upper and a H3 buffer. I have re-posted a picture of the MCR along side of a standard carbine spring for comparison. The MCR is approximately 14 inches long with 34 coils and the stock carbine spring is 11 inches and 36 or 37 coils. I may have miscounted one or two but you get the idea. Both springs are made from the same wire gauge.
Let me start by pasting a portion of an article I found on-line.
"The springs for the rifle and the carbine are the same diameter, and made of the same steel alloy. The rifle springs have 41 to 43 coils, and the carbine springs have 37 to 39 coils. The brand-new length of the springs is approximately 12.75″ for the rifle and 10.5″ for the carbine springs. If you’ve bought a used rifle or carbine, and find that a spring has been shortened by cutting off coils, it should be replaced. (Any rifle that has a shortened spring in it also needs a complete inspection, as the spring was probably not cut without “reason.” You’ll need to find what the problem was that led a previous owner/armorer/gunsmith/hack to cut the spring.)
Springs shorten with use. When a spring has gotten much shorter than the starting length, replace it. As long as a rifle spring is more than 12 inches long, and a carbine spring more than 10 inches long, they are still serviceable. When they have shortened to those lengths or shorter, replace them."
At first, I thought Ares Defense might have just used a rifle buffer spring in a carbine tube. After a second look, that is not the case. It looks like Ares has their own dedicated (custom?) spring.
My question is in regards to aftermarket springs. I have found several companies that sell springs. Heavy springs. Light springs. Flat wire springs. No specifications what so ever other than "heavy" or "light". There must be some kind of standard to work from. I like playing with guns but I can not see buying a dozen springs just to see what works best as an exercise in trial and error. These are machines and not really all that complex. I should be able to take one or two shots and be able to set the gun up.
Up to this point, It has been real easy. The complexity that I am running into is that I am preparing to setup my MCR when I get my Franklin Armory Binary trigger. I had my MCR set up to eject spent shells straight out at the 3 o'clock. Franklin Armory suggests that if the rifle is set up to eject shells at the 1:45 to 2:00 position that you would get better results. They say it's less likely to have hammer follow. If that is the case (and I do not know if it is) then I may have to get into my buffer spring tension.
So help me out guys. How do I even start talking about springs. Length, coils, pounds?
