Ammo availability is something I'll need to consider. My understanding is that .300 BLK is compatible with standard 5.56 AR mags, of which I already have a decent supply. 7.62x39 requires different mags, correct?
I don't know anything about suppressors. I would be looking for the "F150 equivalent" of suppressors - neither the cheapest nor most expensive, durable with a proven track record and good bang-for-the-buck value.
Sub sonic 300 blackout can have Reliability issues in A.R. 15 mags, Heavy and long projectiles ,this is what I have read. I use lancer 300 blackout Mags I have never had any issues with them. Montana Marines 7.62 x 39 Makes a lot of sense, I just might have to go down that road myself :-) all of my suppressors are silencerco they have been reliable robust suppressors, I can highly recommend them.I only have experience with them but there are a lot of nice suppressors out there.I would focus on picking out the pistol carbine first and then worry about the suppressor.
