I can say the Howa M1500 bolt assembly can be field stripped by hand in seconds with firing pin and spring removed. The HACT trigger can be dialed down to about 2 lbs and adjusted upward from there for desired pull. Today’s Howa M1500 action is well built and well thought out and been around in full force since 1975 when issued by Weatherby in their then Vanguard line. Howa barreled actions have been available for sale for the last 30-35 years. It use to be kind of a secret industry wise (their cost and accuracy) as their barreled actions cost about $200.00 some 35 years ago. Solid steel forgings with tight specs and tolerances and a bit more cartridge magazine room. Measuring about 2.88” on their std short action and 3.58” on the std magnum length. Just one perspective on one action and trigger rig.
