Skeletonizing upper and lower receiver

[Kristof]

Hi folks

New guy here. Newer owned any AR. We have a CNC machine available and I decided to build myself a AR10 6.5 creedmoore. I purchased 80% Gen 1 DPMS raw billet upper and lower receiver. Did some research online and saw some guns sold as skeletonized. I like the look so my question is can I do it same with my upper and lower receiver? Or these companies use thicker/stronger material to make them? Nothing crazy just couple slots so I can see my bolt carrier.

I looked at skeletonized AR’s at Palmetto State and the receivers don’t look any thicker than ones without material cut out of them. I would think you should be fine, especially since you’re only planing a couple slots.

could cause more gas in the face?

OP, what's your goal in cutting the receivers?  Weight loss?  Or to look different?  Define what it is that you want to achieve, first, instead of just soliciting opinions on cutting them up. I think it has zero value, but I have no idea what you're trying to do here.
