Griffin Dual-lok 5 vs Dual-lok HRT???

[jetjock07]

Looking at both of these and trying to figure out what’s the main difference. Both look very similar from what I can see. What am I missing? The dual lok 5 is a little longer but lighter and the dual lok HRT uses inconel. I’m interesting in a deviated 556 can

I am currently looking at both of these.
I believe Evan Green over on arcom said the HRT if better for 11.5" barrel lengths
