Went to the range today to conduct a test with my 6920. Just received an H2 buffer and wanted to check it out compared with the H buffer that was stock on the carbine. Ran a 30 round magazine with the H buffer just to get an initial feel. Swapped it out with the H2 and ran another 60 rounds. There was a slight perceived reduction in felt recoil and just a tad more controllability with the muzzle getting back on target.No problems in its function. Now that I have a spare H buffer, I’m considering taking the tungsten weight out of it and replacing a steel weight in my BCM H buffer with it to make it into another H2 buffer. Does it matter in what order that the tungsten and steel weights should be inserted into the buffer casing? Or is it a moot point?
I would trade the buffer or sell it and get another H2. I don’t encourage tearing apart a good buffer.
Got it. Thanks IG.
Good question though! I’ve been resisting doing exactly the same thing with two H buffers to make one H2 and the other standard weight. I figure down the road I’ll get all fouled up since both would be marked wrong. Didn’t consider the order of the weights but surely it’s moot. Guess I’ll buy a couple H2s.
The Spikes ST-T2 for me is the best in reducing the cyclic rate of fire, it works great on my carbine and 10.5 incher without any hiccups that is paired with stock buffer spring length.
Have you actually tried any other buffer? Do you realize that there was high speed slow motion video done and it shows that the Spike’s is in fact no better than other comparable buffers?
Really? can you share please that video.
I’ve used stock H1/H2 buffers which most are mil-spec, had an enidine for some time and it also works wonders, but the ST-T2 tamed my 10.5 erratic rate of fire even with the stock H2 to which I haven’t weighed side-by-side but should be the same.
No. But, you can use Google or Youtube and find it. Enidine is a piece of shit, but what do I know?
I’ve seen those burst as well, ok will google it and the reason I’m asking in this forum to learn and not to get on anybody’s nerve.
I run the ST-T2 in my 16" carbine and my 18" middy. It’s an excellent buffer IMHO and works very well in both applications for me.
What applications are those?
Less muzzle flip, less felt recoil. Possibly more reliability.
Those are not applications. You said you used ST-T2 in “both applications.” My question is what those two applications are?
I honestly don’t see how anyone can tell a difference in recoil between an H and H2 buffer.
Just from what I have read here I’m going with an H2 buffer on my 14.5 middy build. The only other rifle I have is a carbine with a carbine buffer to compare it too.
If it doesn’t cycle reliably ill move down to a H buffer.
Well then I guess my “applications” would be in mid-length and carbine length gas systems if that’s what you’re looking for. Sorry for not making myself clear enough.
Seems like you’d be better off with the Carbine buffer in the mid and the H2 in the Carbine, but I’ve used Hs and H2s in carbines and mids with perfect reliability…
The carbine was a rifle that I bought almost completed and before I knew any better. It will get a major overhaul soon but I wanted another build during this crazy climate before anything drastic happened.
I’m going to see if the middy will run and if not ill change. The middy is going to be my go to rifle I hope an it has all of the quality parts on it. The carbine is nothing spectacular at all.
I’ve used H on my carbine 14.5 and the rate of cycle is a bit erratic or too fast for me thus the muzzle climb is very pronounce, with the H2 Spikes it is less muzzle climb as my rate went down a notch to the comfortable level.
I’ll help you. I’m here to learn too.
