I've used 5 Yankee hill machine receivers, solid stuff, none of that pot metal junk.
BCM enhanced lower parts kits come with a nice upgraded trigger.
I did get 1 bad roll pin from them in my last kit, happens with any brand, check it before you try to install it, opps!
I dont get bargen basement bcg's or pay for fluff iether.
Spend more for a good barrel in the upper, and if it's stainless paint it right now.
Make sure your gas length and buffer/spring match.
The rest is just furniture but a magpull crt stock gets rid of wiggle with thier friction lock.
Dont forget to use anti-seize on the threads.
The little detent spring installation tool for the pivot pin is worth it.
You're comparing apples to oranges here. YHM billet receivers, or any billet receivers are are made entirely different than forged receivers. Pot metal? Non billet receivers are 7075 T6 Forged aluminum. Metallurgists agree that a
forged piece of aluminum is stronger than cast or
billet. The reason being, when the material is shaped under pressure, its 'grain' follows the same shape as the part. Far from pot metal!
You do know there are probably 5-6 give or take forges in the USA that actually forge receivers for EVERYONE. Just to get our facts right here before we get word spreading that forge receivers are pot metal and you now HAVE to buy billet if you want quality. You know how false rumors spread on the interwebs.....

Why should one paint a stainless steel barrel right away??? Those of us that actually shoot our rifles on a regular basis dont waste money on painting barrels because they are a consumable. They are shot out and replaced on a regular basis..... Safe queens and hunting guns that dont get shot often maybe, but you dont HAVE to paint a stainless barrel.
Please explain to me why our gas length and buffer/spring length need to match? Your saying those of us that have built 100's of AR's and the companies that sell them are doing it wrong? Please enlighten me.... We cant use Mid or Rifle length gas with a carbine buffer/tube/spring combo..????? News to me
