It is a Milwaukee 18 gauge. Uses 18 gauge nails up to 2-3/4” long. It is not heavy enough of course for frame nailing but I did use it just to hold square while I drove the screws in. Would have been nice to have a frame nailer but I just don’t have reason to own one. This 18 gauge you will see in upcoming videos is perfect for trim work or installing ship lap. Cycles quick, well balanced. Runs off of my existing Milwaukee 18 Amp batteries.
