Slightly lacking imo - Wheeler Fine Gunsmith Equipment Delta Series AR Armorers Bench Block

I bought this to install an A2 style front sight, so it works perfectly in that regard. However, there's no space for a low profile gas block. I found this a little annoying tbh. Does the entire lower receiver need to be blocked to install the bolt catch? I've never had any trouble installing one. I'm not sure what needs to be hammered on the side of a lower. The toughest thing to install is the takedown detent and there doesn't seem to be any special provisions for that.
I'd much rather have a space for a low pro gas block. Otherwise, seems solid.
