Mesa, AZ — AR-15 lower receivers

“`html

Opening paragraph

AR-15 Lower Lab ships forged 7075-T6 aluminum lowers to Mesa, AZ. These are machined to Mil-Spec dimensions with a focus on tight tolerances. Local buyers order from us because we don’t outsource anodizing—it’s done in-house for consistent hardness. No laser engraving that wears off. Just functional parts.

Mesa, AZ gun laws

Arizona requires no permit for firearm purchase or concealed carry. There is no state registration for rifles. Lowers ship to your local FFL for transfer. Sales tax applies.

Shipping to Mesa

Orders ship within 3 business days. We use USPS Priority Mail for lowers under 3 lbs. Your chosen FFL in Mesa must accept transfers from private sellers—confirm this before ordering. Expect to show ID and complete a 4473 form at their counter. Lead time from order to pickup averages 7 days.

Why builders in Mesa order from us

Our Type III hardcoat anodizing holds up to desert UV exposure better than spray-on finishes. The trigger pocket is machined with +0.002/-0.000 inch tolerance to prevent slop with common aftermarket triggers. We don’t use cast aluminum like some budget brands, so these won’t crack under sustained fire at Usery Mountain ranges.
