Now that you’ve bought one, build another one.
Seriesly.
If you can change a tire, you can build an AR.
Initial startup might cost a bit more because of the tools required, but you only have to buy those once.
I built mine entirely at my computer desk.
At least get a spare receiver, or 2. They take up very little space in your safe and if well taken care of, will grow up to be a full sized AR one day.
Naw, don’t just build one, build a piston version and purchase a .22lr CMMG conversion unit to use for practice. I built three piston versions. The best two are the Adams Arms and the Osprey. I prefer the Osprey Defense because it is virtually maintenance free and light weight out front.
