Removing the bleeping A2 sight tower so I can put on a free floating guard and low profile gas block was as difficult as advertised. A medium sized sledge hammer, a quality tapered pin punch, and about eight mins of frustration got the pins out.
Don't have the new guard in hand. I screwed myself by installing an Osprey gas piston kit (it was laying around)--it severely limits the guard options--and I'm too stubborn to convert it back.
Next, I get to spend more on optics than the rifle cost. That doesn't seem right.
