Hi Im new here
I am looking to build my first AR and with all the millions of sites, I'm lost on which lower and upper that I want, I believe I want a billet aluminum 7075 without trigger guard but I don't know which company's product to invest in. Any suggestions would help. Thanks in advance. |

For your first build, go with an Aero Precision blemished mil-spec forged receiver set. Trust me, you will end up selling your first build because of all the things you learned. This goes for your second and third as well. By your fourth build, with lots of research, you will have figured out what you like and don't like. If you build a mil-spec mid-length 16'' carbine then you will most likely make a few bucks when you go to sell it, then take the money and knowledge and build something a little nicer, like a Spikes or YHM clone with a low pro gas block and a free floating quad rail. Then sell that and build what you really want. If you go about it this way, then hopefully you won't end up like me (and everyone else here) with tons of expensive parts that you decided you did not like and cannot sell.
I would also start doing some research on billet lowers, assuming that you are going on the assumption that they are stronger than forged. In reality, they are not. In fact, forged receivers are slightly stronger than their billet counterparts. With that said, there's nothing wrong with billet. Most billet receivers have some nice features and are usually good looking. Just don't let anyone tell you that billet receivers are inherently stronger, pound for pound, than forged. While most billet receivers are stronger than mil-specs, they are thicker and, therefore, heavier. I know this doesn't exactly answer your question, but I hope that makes sense. |

If this is your first build, please know that several (but not all) of the billet lowers also use set screws in lieu of the bolt catch roll pin, so check before you hammer a roll pin in there and mess up the threads. Some also use a set screw option to capture the rear detent spring. If you decide to use it, you may need to cut 1/8" off that spring to get it to work correctly. Here's a couple of reference sources to help you out, in case you haven't seen them. http://www.ar15.com/forums/t_3_4/226782_Assemble_your_own_LOWER__UPPER__FREE_FLOAT__TRIGGER__GAS_BLOCK___Step_by_step_instructions_.html http://www.ar15.com/forums/t_3_4/615304_Step_by_step_video_on_how_to_build_your_lower_receiver.html http://www.ar15.com/forums/t_3_118/395777_Simple_fix_for_the_rear_takedown_detent_spring_blues____.html Now, in answer to your question, Seekins Precision, CMT Tactical, and Aero Precision all make nice billet receivers. The Arfcom store also has a nice billet receiver set.
