AT3 Tactical LR AR-15 Lower Build Kit – Luth-AR Precision Furniture
Features
- Includes the lower parts needed to complete a stripped AR-15 lower receiver for a long-range or precision-focused build
- Luth-AR MBA-1 fixed rifle stock includes adjustable comb height, length of pull, and 3-axis butt plate adjustment for dialing in fit behind magnified optics
- Luth-AR Chubby Wing grip gives the support hand a wider, more vertical grip profile for bench, prone, or supported shooting positions
- Includes a 1005 Tactical two-stage trigger for a more controlled trigger press than a basic mil-spec fire control group
- Uses a rifle-length fixed buffer tube kit instead of a carbine buffer assembly
The AT3 Tactical LR AR-15 Lower Build Kit with Luth-AR Furniture is built for finishing a stripped lower on a precision-leaning AR-15 rifle. It combines standard lower receiver controls with a two-stage trigger, Luth-AR Chubby Wing grip, MBA-1 fixed rifle stock, and rifle buffer tube kit, giving builders a lower setup better suited for supported shooting and optic-heavy rifles than a basic carbine furniture package.
Note: This kit is not assembled. Stripped lower receiver is not included.
