What is it doing that makes you think it needs smoothed out?
I always keep one of each buffer on hand to see what happens, a few springs on hand won't hurt either, but there are lots of variables.
Think for yourself. Question authority.
I put a Damage Industries chrome silicon in my M&P15 and it's great. (And very inexpensive.) They seem to go on sale pretty often as well.
Nothing really I just fried a guy's rifle at the range and it's seamed to cycle a lot smoother than mine. The only difference between the 2 rifles were those two components. Mine eats whatever ammo I put through it so I really don't want to do anything drastic to it. But if swapping those two parts lets me keep the same reliability and smooths it out I'm thinking it's a go. I guess what I'm asking is if doing this has any downsides?

Ordered the sprinco white standard spring and blue enhanced. My buddy has an H and an H2 I can try so I ordered the Spikes ST-T2 to give it a try. The listed weight has it in between an H and an H2 so I'm curious if it might be in the sweet spot. Especially since I've been known to shoot some weak Wolf and Tula.
Thanks for the advice!

Chances are your rifle is intentionally overgassed so it will function with lower pressure .223 loads. The best way to address the problem is with an adjustable gas block, preferrably one from SLR Rifleworks. It allows you to reduce the volume of gas ported to your BCG, which reduces BCG velocity , recoil and muzzle jump. A heavier buffer increases reciprocating mass which increases muzzle jump.
Brass ejected from your rifle should not strike the brass deflector on the upper receiver.
Weaker ammo may not properly cycle your rifle if you install a heavier buffer.
Buffers and springs are bandaids and snake oil. Adjustable gas blocks are an unnecessary failure point at one of the most critical points of keeping it a semi-automatic rifle. If it runs, leave it alone. If you want it to shoot flatter, screw on a comp/brake. If you want to change components, buy a barrel with a correctly-sized gas port.
