Troy Industries Folding Battle Sight, if you want metal.
Magpul MBUS Gen II, if you want polymer.
I already have a carry handle scope. I'm happy with it for now. I am getting a flat top receiver and will be picking up a detachable carry handle. My question is, what type of flip up front sight would you recommend to replace the traditional A2 type front sight? Thank you
I'd leave the A2 sight as is unless you are planning to go with a longer rail and want to cover the gas block.
The way I read this, you are planning to swap your barrel into a new A3 upper receiver, then replace your A2 front sight, with a railed gas block?
On this new flat top upper, you are going to install a removable carry handle, then mount an optic on top of that removable carry handle? Then you believe you need a flip-up front sight for the upper, as opposed to a fixed front sight base?
I'm going to go out on a limb, and say UTG probably makes a front sight that would fit that set-up.
