H1 or H2 ?

I just went through this myself. From factory they come with "HH" aka H2, so I'd recommend that weight. I also opted for the Spike's Tactical buffer kit, they're labelled as a "T2" Give or take the same weight, the "T" is because the weights are tungsten.

IUR is an H2
Spikes uses tungsten powder.

HH but the CAF is moving towards HHH

I have a h2 in another rifle I will try.

The RCMP ones are also currently HHH. I did an open google search on " RCMP C8IUR " and found the specs listed.

Remember guys, we're not running in full auto. I run an H buffer in mine, works all day long in my semi IUR.

Are the rcmp running semi and select fire?

The Colt Carbine H2 buffer was OOS on Brownells when I was looking so I went for the Spikes Tactical T2 (which had much better availability). Also got CS springs from Brownells.

With that my 15.7 blemish IUR ejects at 4 o'clock. My 14.5 Norc upper ejects at 2-3 o'clock with the same setup.

Semi for on duty. But they do use some full auto during training.

I'm also running a T2 with my IUR, and found the same thing. We were actually able to setup a bucket over my right shoulder to catch the spent brass, lol.
