I like using my green dot sight over the irons for quick acquisition and whatnot but I would also enjoy having the irons available so I can keep my skills with them sharp and also as a back up for if the dot fails...so my question is, are there any truely good gas blocks with either just one top rail or simply a built in flip up sight that is also PINNED? the main concern is the pinning, as all other gas blocks ive seen are either set screw or clamp and I don't believe I would ever fully trust a gas block of this type. I believe pinning it is the only way to go. So are there any pinned gas blocks with either a top rail or simply a built in flip up front sight? I know about VLTOR's, but I was hoping to find something a little more reasonably costing. I don't think it should could two hundred some dollars just to have the proper method of attachment!
