Pros & Cons


  • Magnesium housing makes the gun so light, it’s nice and easy to handle
  • Sequential and contact trigger system with Dial-A-Depth control for precise countersinking
  • Ultra-quiet rear exhaust directs air away from the user and filters the air inlet. It dampens the sound of the nailer so when you’re working in tight quarters like inside a cabinet or inside a closet, it’s really a lot quieter
  • Low nail lockout prevents dry firing
  • Quick release nosepiece is really easy to open and clear jams


  • Bottom loading magazine is not very user friendly, you have to work the nail past slider to get them in and out which is a real hassle when you’re trying to change sizes in the middle of working and also if you have short clips and nails, it’s a hassle to work them back past the stop to get them into the gun
  • Occasional nail jam
