So, I recently added the CMMG Dissent .300BO pistol (6.5”) to my “arsenal”. It’s going to be suppressed as a home defense and/or travel PDW when out of town.

Question. I want a slightly longer barrel and upper for more than just subs and I want to keep it in the “pistol barrel” lengths, so looking at the longer 10.5” barrel, should I consider skipping 300BO and getting the upper in 5.56 instead? I figure it would be cheaper for training and drills. I would likely still run it suppressed but just thinking that may make the Dissent a little more versatile. Thoughts?

Yes, the price of the upper is pretty damn expensive.

Price it on gun.deals. I got my Dissent upper w/lower adapter brand new for around 1100. What you're saying makes sense though. 5.56 would be cheaper to shoot and is a good length. If you ever think you'll hunt with it, it would make sense to such with 300.

Matches my reasoning. I don't plan to use it for hunting, so the 5.56 may be better for training...
