I am still searching, but if it functions as a AR 15 lower receiver, I rather save my money for a red dot/scope, sights, and accessories. I want to build an M4 lookalike and then I want to have a 18 inch SPR type. Then the rest of the money is all going towards ammo! I need to go check out Fat Boy Tactical sometime in the next week or so and then go have a range day and report back. I am still waiting on some parts for my AR Pistol.
I have built 3 guns on Anderson lowers and with other various parts. They have all assembled easily and functioned just as well as guns I've put together with lowers costing double or triple the price. If your gun is built on a high end lower you will get a nicer finish, less noticeable machining marks, and a bit more street cred but thats about it. The most recent Anderson lower is the first I have built and not had cerakoted so I will report back on how the finish holds up but my guess is not very well.
