I know this is a pretty common question on forums, sorry guys. I did a bit of looking around and im still scratching my head.

So I took out the car buffer and buffer spring, which I had not done in a long time, just out of pure curiosity. I see on the rubber pad on the buffer weight a circle the size of the buffer tube vent, and it's pretty obvious looking down into my buffer tube it's been whackin it. Would explain why ive been feelin extra recoil on some shots. Glad I took it out before any real damage occurred.

Now, I'm lookin at buying a heavier buffer, mostly either the spikes ST-T2 which I've been reading is between the H and H2, or a BCM H2 buffer.

The ammo I'll be firing will either be 5.56, or stout 223. Should I get the H, H2, or ST-T2? I'd like to keep the recoil down a bit, but still keep the reliability for plinking rounds if possible.

Any advice? I'm running a BCM upper, with a RR NM lower.
 
I run a ST2 buffer in mid length upper (with a Dynacomp) and it's very soft shooting. 5.56 is noticeably more energetic than Russian .223, but soft recoil all the same.
 
I've been pretty happy with either the H or H2 on my 16" BCM midlength. The H2 isn't 100% with low power rounds but almost. The H doesn't short stroke. As you said, the ST-T2 is about 1/2 oz more than the H and 1/2 oz less than the H2.

Since you have a standard buffer you could get the H2 or even H3 and swap steel and tungsten weight to get the weight you want if you're into DIY. (Knock out the roll pins to get to the weights.)
 
Well, the H2 seems to be a bit cheaper than the T2, and now I'm thinking I could just use the H2 for 5.56, and swap out for the car buffer for commie 223.
i probably wont be playing with the weights, since this will be a HD gun, but if I find some spare crap parts that's a great idea and I'll keep it in the back of my mind.
thanks for the input folks, i appreciate anyone else chiming in with their experiences with the ST-T2 or H2 buffer
 
Yeah, if you swap internal weights then it's hard to remember what's what unless you re-mark the face of the buffer. A scale will tell of course.
 
I have an ST-T2 and a BCM M16 BCG in my BCM Middy and it works very well.
 
In all of my BCM and DD mids, I run H2 buffers with Blue Sprinco Springs. If I know all I'm going to be firing is 5.56 for a given class or range session then I'll run a Sprinco Red Spring with the H2 buffer.

I feel like the spring is rarely talked about when people want to mitigate perceived recoil but it's a very important piece of the puzzle.

If you're going to upgrade your buffer then upgrade your spring as well.

Well, hell..
My choice now is between an H buffer, or an H2.
After doing some research, all BCM carbines, midlength or m4 config ship with H buffers, same with Colt and their USGI M4.
Am I being too overzealous jumping onto the H2 immediately? The weakest ammo I'll be shooting is American Eagle, or remington bulk.
I just bought a sparc vortex RDS so every dollar hurts now, and Im really considering the H, if theres no big difference with the H2 in perceived recoil, with possible short stroking issues in the H2.
Its kind of hard to justify the extra bucks now for the spikes, not to mention i wouldnt be able to disassemble it to switch out the weights, worst comes to worst.
I'm going to sleep on it, and order tomorrow. Thanks for the input guys!

No, you're not being overzealous. Using an H2 buffer with the stock spring, you should be able to cycle everything down to cheap Tula steel.

You really should think about upgrading your spring as well. Together, the Blue Sprinco Spring and the H2 buffer will reduce a decent amount of perceived recoil. The heavier buffer and spring will also reduce bolt bounce.

I like the st-t2, but an h2 is my next choice. That goes for all length gas systems with a collapsible stock. I dont use carbine buffers.

The dead blow of sand (tungsten powder) in the st-t2 is noticeable and I prefer the perceived softer recoil.

My mid length was actually over gassing. My guess is an over sized gas port. I was able to correct the FTE issue created by the over gassing by closing down the adjustable gas block a little but I don't want to create a bottleneck in the gas system to clog after a little bit of use so I opted to try the ST T2 to do the major work addresing the issue. Then I can fine tune from the adjustable gas block. Still, being my first AR build you guys have got me thinking about springs now.
 
Powdered tungsten actually.

Really? Wow, i have never read the specs that are all over the internet and on the web site were i ordered mine. lol.

"dead blow of sand" was a description of how it feels. Tungsten powder, tungsten sand....whatever. ;)

I've ordered the H2 buffer, and I can't wait to hit the range when it gets here in a day or two. I'm thinking about the buffer spring too, but I'll only replace it if I need to troubleshoot or get another EBR disease flare-up. I mean my rifle is still pretty dang new, but after a sling and maybe light system :D its on my list.

you guys rock, thanks for the replies and ideas. :)
