Change the wire, that is all you need to do.I just want to get rid of the "twang" and smooth out my cycling in my 516 without having to do anything additional other than put the flat wire buffer in. If I have to change the buffer and adjust the gas settings to shoot 55 or 62 grain ammo unsurpressed, I will not go with the flat wire spring and return it to my LGS.
The Gen2 used an H buffer marked with an "H" in the center of the face. Additionally, I had an H2 to compare against and it was definitely heavier than the Sig buffer. I swapped for the H2 and no issues.SIg 516 uses H2 buffer, as far as I know. I dont think the gas settings will need a change, due to the wire being same, except flat and made of a material that lasts longer.
@anbuyoshi - are you saying that you have a Sig516 Gen 2 and had the H marked on the buffert (which is what mine is marked), and you changed the buffer with the Tubb flat wire buffer spring to the H2 buffer and it chcled with no issues? If so, did you order the H2 Buffer for om SIG? Thanks! I appreciate ALL help!!!
You shouldn't have any function issues.@anbuyoshi, I run the Spikes T2 buffer with no issues in my mid-gen2 516.
That's all it is, arguments based on what someone thinks and not any real experience with a problem. I run T2 and T3 buffers from Spikes, thousands of rounds and no issues. They are a solid product I would stake my life on.You shouldn't have any function issues.
It's a product introduced looking to solve a problem that doesn't exist. I've read different arguments about how it may or may not cause additional bolt bounce, but I don't care enough about it to try. Standard H2 is perfectly fine.
Only problem with the Geissele is the buffer is proprietary, standard buffers will not fit in the spring.I'm aware of the pros to flatwires. The pros just aren't sufficient enough for me to go out and purchase all new springs for all of my AR style rifles. The H2 buffer was, less the rifle length system on my SPR style AR.
When my buffer springs wear out (probably not for a long, long time) then I'll likely change them to the flatwire or even Geiselle's braided spring.
Correct, but they give you one with it in H1 weight. You'd have to buy another tungsten weight from their sight to make it an H2.Only problem with the Geissele is the buffer is proprietary, standard buffers will not fit in the spring.
Ammo plays a big part in cycling too. I use 62 gr ammo, same manufacturer every time. This makes me consistent, as well as making rifle have no abrupt changes.. Try a low grade bullet and a high quality round, and see the difference in cycling.I have thought about the MCX, but I am not sold on that rifle at all! Way too many cycling and malfunction issues with the MCX for my liking.
I am so much more of a 516 fan and will just deal with the "sproing" since I am a weekend shooter and not in a Combat zone all day. I'll live with the "sproing" sound! More importantly, I am hoping the cycling will be smoother! Unfortunately, It'll be about a month or more for me to be able to shoot my 516 to give a report on cycling!!!
