Any 7075-T6 A2 lower or billet. Brand doesn't mean much. An in spec A2 or billet lower is exactly that.

What upper are you planning on?
I'm not a fan of frankenguns, so the upper would dictate the lower, and vice versa. |

Whatever you get, TEST FIT BEFORE PAPERWORK!!! This is so very important. Learn from my experience
Imo, Mega makes the most precise stuff. |

Make sure it's in spec before sending off the paperwork and $200 to the Feds for 'permission' to SBR it. I've used a few Andersons with no issues, but if billet is your thing Mega is rock solid AFAIK. |

Iv'e got two BCM uppers and one fits very tight while one has a bit of play when placed on the same lower. |

Iv'e got two BCM uppers and one fits very tight while one has a bit of play when placed on the same lower. Let me put it this way...I am currently waiting on a replacement tax-stamp for a replacement lower, because the lower I got with a complete SBR only fit that upper, and was deemed out of spec both by a third party company, as well as the company that made it after I sent it back, and that upper was FUBAR. So I had a lower, that only fit hat FUBAR upper. The whole gun is having to be replaced. So do yourself a favor, and CHECK YOUR LOWER! Uppers are just money, who cares? Lowers are time. Time is priceless. |

I am sure you guys get tired of me dropping in these threads however.....
Might I recommend a 2A-Armament BALIOS-lite for your SBR build.

I have 8 SBRs, and only one is a frankengun. And that one "frankengun" SBR is tough to tell because it's a KAC lower with an AAC upper that has a KAC handguard. It's also been cerakoted as well, so it looks like a factory KAC SBR. |

Department requirements are different from personal preferences. If the OP had department requirements, he wouldn't be here asking which lower to SBR. As you probably know, MOST uppers is that they are not marked with a company name, only a forge mark. And those marked with a company name are often forged by a different company anyway. And a forge often makes uppers for many different companies, and has been noted, may or may not be marked with a company name. A lower is the same way. Many companies do not forge their own lowers, and often use different forge companies from run to run. So, to avoid the "frankengun" syndrome, one must only use a lower, along with an upper marked with the same company name. Even then, unless the company forges their own uppers AND lowers, they may very well be forged by two different companies. The fit and finish match may, or may not be better than a frankengun. If one wishes to match their upper and lower, more power to them. For many, it will not matter. And few will be able to tell if an unmarked upper is matched with a correct lower. Many would prefer to buy a cheap, but in-spec upper/lower, and spend money saved on a better barrel, optic and trigger. |

Unless the AR came from the same factory as a complete rifle or pistol then it's a "frankengun." Simply matching two receivers of the same brand doesn't mean it's not a "frankengun" if they have been built by one shooter or another. |

Simply using an upper and lower marked as made by the same company will not magically make the rifle not a frankengun. It may not look like a frankengun, but it will still be a frankengun. It will never be a factory made rifle. |

I'd look at the Quentin Defense ambi billet.
Bolt release only on the right side of it, and I've got 2 of their non-ambi lowers and the finish on them is excellent. They also have Army, Navy, Marines, Air Force, and Coast Guard engraved lowers for $125 right now. The bolt catch is threaded and no roll pins are needed for finishing the lower. They can also engrave it for you for your Form 1.
