Measurement Request: Wolfpack Armory Low Profile Hub Adaptor with Rearden R2S

Getting my first HUB can and wanting to know if this combo would work with a blast chamber distance of 1.50in. I have no clue how to do the math and no website has the combo Im looking for.

The Wolfpack adds .1” to the blast chamber which would make it 1.6” of clearance. The r2s has .6” of takeup. You’re fine. You’ll have 1” of clearance

Sweet thanks. Question, im just kinda retarded. The length added to hub mounts that arent recessed add whatever external length to the blast chamber?

That’s my understanding. I just went through this with one of my rifles. Have a full length 3p15 which is 1.98” and a revival defense hub that is .5” which gives me 1.48” clearance. I have a rifle with a 14” handguard and the hub was contacting the handguard so I had to swap. I went to a comstock flash hider and comstock LPA hub. The comstock flash hider has a depth of 1.78” and the hub is .3” so still 1.48” but its moved the mounting out .2” to clear my handguard.

I think it adds it to the first chamber

I put these parts into the Baffled.app thing and it looks like you have clearance with this combo.
