Nampa, ID — AR-15 lower receivers

“`html

Opening paragraph

AR-15 Lower Lab ships forged 7075-T6 lowers to Nampa, ID. Our receivers are machined to ±0.002″ tolerances with Type III hardcoat anodizing. Local buyers order from us because we don’t use cast components or shortcut the stress-relief process. Each lower is proof-marked and ships with a completed ATF Form 4473 for your FFL.

Nampa, ID gun laws

Idaho is a permitless carry state with no waiting period for firearm purchases. There is no state registration requirement for AR-15 lowers. Sales tax applies unless shipping to an FFL outside Ada County.

Shipping to Nampa

Lowers ship via USPS Priority Mail to your selected FFL within 3 business days. We include a prepaid return label for any receiver exceeding tolerance checks. Most Nampa FFLs charge $25-40 for transfers. Lead time is 7-10 days from order to delivery at Snake River Sporting Goods or other local dealers.

Why builders in Nampa order from us

Our anodizing holds up to Owyhee County dust storms better than spray-on coatings. The trigger pocket is cut for Geissele triggers used by competitive shooters at Nampa Rod and Gun Club. We machine the takedown pin detent channel at 0.125″ to match Idaho Armament jigs sold at local shops.
