Speaking of ARs
Awhile ago you did a post on purchasing ones first 1911. Any chance on doing the same for a AR?
I honestly don't think I know enough about ARs to do that. While I speak from personal experience regarding the 1911, that experience is widely varied, and it's something I studied pretty deeply.
If I were to attempt to do the same with the AR-15 and it's many variants and uses, I would be doing my readers a disservice. Officer.com has an excellent AR-15 buyer's guide up. The Brownells videos I linked to give a lot of expert info on how to build one. There are many more people out there that give solid recommendations. It seems Colt and Bushmaster are the ones to save up for.
For my money, if I did not own one, I would acquire one now. I would keep things simple, an open sighted carbine, with plenty of magazines. Use tactics to gain advantage so you may use the carbine effectively. Tactics trumps equipment any day of the week.
My two pesos.
