Super useful
I purchased this tool because I am always looking for the next tool that makes doing things easier and better I don’t think I would use it to tighten a barrel nut or a muzzle device but it works well for lower work the gas tube roll pin station is great it even works with the Rifle Speed adjustable gas block if you remove the adjustment knob and pin plate

This product works great for repairs or assembly of a lower receiver. Can be adjusted to ease installation of small parts. Durable constuction and should last a long time. Good value too.
