I have a lower with an H2 buffer that is usually mated with a carbine upper. I'm purchasing a mid-length upper. Can I use the lower with my new mid-length upper? Should I compromise and get the standard H buffer? The Carbine has the semi BC and Mid will have an auto BC |
Your H2 buffer should work with a midlength upper but your bolt cycling speed would be slower, if you would prefer to make it faster go to the lighter H or even standard buffer. I only use standard buffer on my midlength carbine and it works fine, in my own opinion and experience the midlength gas system don't even need the H buffer. I also use an auto BCG on my midlength carbine, the only upgrade that I made was I added an extractor O-ring, the extra power extractor spring is not required. |
I've run my 16" middy with an H2 shooting commercial, handloaded, Q3131 and XM193, Remington 45gr Frangible, and it all runs fine. |
there's the catch, without testing your personal loads, its not possible to give a positive answer. You'll have to test it to be sure, then, if necessary, modify you load or change buffers, etc |
