Serialized lowers · parts kits · triggers · stocks
The half of the rifle that carries the serial numberStripped and complete AR-15 lowers from licensed makers, and every part it takes to build one.
A lower is a firearm and ships to the dealer you name; a parts kit, a trigger, a buffer and a stock are parts and ship to your door. The build sheet tells you which is which, the guides take the build in order, and the price is re-checked against the distributor when you order.

Build notes from owners
Written by people who own the gun“It's a good little pocket gun. Has a really long trigger pull but with no safety thats a good thing. Folks with larger hands might want to put it in a pocket holster. Over all the size is good for pocket carry and its hard to beat the price.”
Ruger LCP Compact .380 ACP Black Pistol“This was my first Walther PPS M2 LE. The pistol performed as I had hoped and expected. All three magazines fit nicely and ejected easily. I look forward to experimenting with different brands of ammo. I am completely satisfied with my purchase.”
Walther PPS M2 LE Edition 9mm Blue/Black Pistol“Feels nice and solid, I haven't gotten a chance to shoot it yet but I sure will be tomorrow to see how it feels to shoot it. I done had the g2s and g2c now I got the g3c”
Taurus G3C Compact 9mm Blue/Black Pistol“Another awesome revolver. The stainless finish on the Taurus is amazing. Shoots like a dream. Awesome edc. Pistol. 5 out of 5”
Taurus 605 .357 Mag Stainless/Silver Revolver“The fit and finish on this gun is really nice for the money. Shoots great and its beautiful to look at.”
Taurus PT92 Full-Size DA/SA 9mm Stainless Pistol“I was hesitant to buy this Taurus at first but after I put a little over 400 rounds of different brands of ammunition through it I was impressed. Even my carry ammo feed well. I'm former government employee and when I carry cancelled I don't want any print of a weapon on me what so ever and the Taurus GX4 micro compact 9 does just that.”

All categories →A lab for the half of the rifle that carries the serial number
AR15 Lower Lab is an online shop built around the AR-15 lower receiver. Serialized stripped and complete lowers from licensed makers sit at the front, followed by the lower parts kits, triggers, buffer tubes, buffers, springs, stocks, grips and ambidextrous controls that turn a bare forging into a working rifle, and the complete uppers and rifles that finish the job. Every lower ships to the licensed dealer you name for the background check; every part ships to your door.
We sell finished, serialized receivers only. There are no unfinished receivers, no receiver blanks and no tooling to complete them here, and nothing on this site converts a rifle to automatic fire. The guides follow the build in order: why a lower is a firearm and how it transfers, the rifle-or-pistol decision, installing the parts kit, buffers and stocks, and controls and grips. Your town's dealer transfer rules are on the ship-to pages.
