Hi, I have a the 527 carbine in .223 The rifle has a nice trigger using the regular trigger and by pushing forward on it the trigger is then set(single set trigger)and it is then great! Dont know what you mean by the heavy,s but the the rifle comes in 7.62x39 as well. Mine shoots the 60 grain partion (Federal factory Premium) loads into less than 1.5 inches for 3 of them at 150 yards. This is the only load I have shot in mine and it worked great on a 150 pound doe shot at 150 yards(post and pics somewhere in the rifle thread here)It may shoot better with lighter bullets ? Overall I really like the rifle and with scope (4x Leupold compact)and sling(simple strap)and loaded(5 rounds in the magazine) weighs a tad less than 7 pounds. Very easy to carry on shoulder and carry in the hand as I hold it with the Magazine resting on the side of my little finger and let the muzzle point at an angle toward the ground.
