The NT65MA4 is a 15 gauge angled finish nailer that accepts DA nails from 1-1/4 to 2-1/2 inches and weighs 4.2 lb. The angled magazine reaches into corners and tight spaces for crown molding, baseboard, door casing and stair work. A selective actuation switch lets you choose bump or sequential firing.
The thicker 15 gauge nail holds heavy trim and jambs better than a 16 gauge, at the cost of a slightly larger hole to fill. It needs a compressor and hose, and a lightweight 4.2 lb body reduces fatigue on a long day of trim. Compared with the 16 gauge NT65M2S, it drives a stronger nail but leaves a larger hole.
Keep it oiled, drain the compressor and keep the magazine clean. Metabo HPT is a trade brand, so nails, parts and rebuild kits are easy to find, and the gun can run for years. Set the compressor regulator to the pressure printed in the manual, usually 70 to 100 PSI for trim, and sink a few test nails into scrap of the same species first, because hardwood trim needs more pressure than pine and a depth setting that works on one board can split the next.
