AT3 16 Inch 5.56 JNL Ready Build Kit – Pencil Barrel M-LOK Rifle Setup

Features

Just Needs Lower kit includes an assembled 16 inch 5.56 NATO upper plus the parts needed to complete a stripped AR-15 lower receiver
Lightweight pencil-profile barrel keeps the front end easier to handle than heavier government-profile builds
Mid-length gas system pairs well with the 16 inch barrel for a smoother carbine setup
Assembled upper includes AT3 billet upper receiver, SPEAR M-LOK handguard, black nitride BCG, and selected charging handle and muzzle device
Lower build components include Magpul CTR stock, MOE pistol grip, Magpul trigger guard, buffer tube kit, lower parts kit, and AT3 enhanced Nickel Teflon trigger group

The AT3 16 inch 5.56 JNL Ready Build Kit is built for customers who want the upper receiver already assembled and only need to supply a stripped AR-15 lower receiver. This kit pairs a lightweight 16 inch pencil-barrel upper with Magpul CTR furniture and an upgraded AT3 Nickel Teflon trigger group, giving the build better handling and a cleaner trigger than a basic rifle kit.

Note: This kit includes an assembled upper receiver and lower build components. Stripped lower receiver is not included, and lower parts are not assembled. Built-to-order upper assemblies may require additional processing time before shipping.
