I'm trying to decide which to use. I really like the look of the Arms A frame front, but it uses hex screws to secure it to the barrel. I don't know how secure this is, as I hear of a lot of people having trouble with it canting. However it does have a bayonet lug, so I mean it has to be able to keep up right. Another option is the YHM one, which is a lot cheaper, but I've read reviews of the front sight being wobbly at times. Are there any that use taper pins, as I'm much more comfortable knowing that those are on my rifle? Any suggestions would help. Thanks

I wouldn't worry a bit about the durability of set screw or clamping attachments. I have a low-profile gas block that's attached with set screws, and it gives no trouble.

Were I to use a gas block/front sight though, I'd probably go with a PRI even though they're kind of expensive, just because I really like their front sight.

There is a pin on version of the A.R.M.S.. It is called the #41 B-L-P.

I have the Vltor model and like it.

I have the ARMS, I like it,

Lol I hate the PRI front sight.

I have the YHM clamp on gas block/flip up sight on a pistol and it is rock solid
