Rock solid insanely durable. - Samson Vertical Grip, M-LOK

I got the stubby version of this grip to use as a handstop to pull back against. There's honestly not much to say about it, it looks great and it is ROCK SOLID. Despite being metal, it still doesn't weigh all that much and is absolutely worth the extra durability. Throw some loctite on the threads (including the main big one)and it doesn't budge. I can slam this thing down onto a rock and the handguard would break before this thing. If you want a metal grip this is the one for you without question.
