The Milwaukee 2839-21CT is a cordless 15 gauge finish nailer built for trim, crown molding and baseboards. A nitrogen air spring, brushless POWERSTATE motor and REDLINK PLUS electronics give it a pneumatic-like response with no ramp-up between shots, and it sinks nails to depth in hard and softwoods while leaving clean holes. It runs on any M18 REDLITHIUM battery and fires up to 750 nails per charge on a CP2.0 pack. Reviewers rate it highly for consistent depth and the freedom of no hose, though it is heavier and bulkier than a pneumatic gun and needs the usual battery and gas-spring care.

Owners rate the nailer highly, praising pneumatic-like performance, repeatable depth and the convenience of going cordless on trim work. Complaints center on weight and bulk compared with air tools, plus battery runtime on long runs.
The Milwaukee M18 FUEL 15 Gauge Finish Nailer is a cordless nailer that works without a compressor or hose. A nitrogen air spring mechanism sinks nails to depth in hardwoods and softwoods and leaves clean nail holes that are easy to fill. It is used for finishing nails in trim, crown molding, baseboards and similar work.
The nailer combines the nitrogen air spring with a POWERSTATE Brushless Motor and REDLINK PLUS Intelligence for a pneumatic-like response with no ramp-up time from nail to nail. REDLINK PLUS Intelligence communicates between the tool, battery and charger for optimized performance and overload protection. The brushless motor gives longer life and higher performance.
The compact, ergonomic design reaches into tight spaces and limits fatigue. With an M18 REDLITHIUM CP2.0 battery pack, it fires up to 750 nails per charge. It works with all M18 REDLITHIUM batteries and uses no gas cartridge.
