I'll give you my spiel about rifle cans....
They are dumb, heavy, expensive, dirty, affect function, and have essentially no place for the vast majority of AR owners.
That out of the way, I like having them. I want a new one. It is NOT a rational decision. Which, then, begs the question - why am I trying to use reason to evaluate which non-rational item I will buy? It comes down to money, frankly.
Given that it's a toy, and a waste of money, and a frivolous purchase, I want to spread all that nonsense over as much use as I can to take the sting off. that means I want a can that will work on a 5.56 AR, a 7.62x39 AK, a .308 bolt gun, a 6.x AR upper, an SBR, an SPR, and any combination thereof or in-between.
This means that I've come up with some criteria that any potential can must meet for me to even consider it...
- .30 Caliber
- ~7" OAL
- <16 oz. (<14 oz. even better)
- ~1.50" OD
- <$1k retail with one mount
- Availability of 5.56 hider mounts that work with the can
- Availability of 5.56 brake mounts that work with the can
- Availability of 7.62 brake mounts in 5/8x24
- Availability of 7.62 hider mounts in 5/8x24
- Availability of 7.62 hider mounts in 14x1 LH
That's my list. Yours may be different. But I think that when you're talking about the time investment in getting the can and the massive depreciation across the used can market, you should come up with a list.
