Edit;
First off I swapped out the 700mm .25 barrel for a 500mm .22 kit with a DIY carbon shroud and then the 580cc bottle for a 300cc unit.
After that changed out the Aztec 5.5 x25x50 for one of the newer Immersive 10x40 prism scopes. Love my Aztec scopes but they are a bit heavy when compared to the small fixed power prism scopes. The glass on both is clear and bright and looks to be very comparable. The only thing I will be loosing is the powers from eleven to twenty-five.
Then I changed out the K&L Gen2 trigger guard and Arca adapter for the newer Gravity Rail which has both an Arca and Picatinny rail also but it is a lighter and more compact unit.
After I installed the Gen2 K&L rail on my M3 I stole the mono-pod from the compact .22 and put it on the .30 M3 as well.
Dropped over a pound from the gun with these changes. So, it's down to 7lbs. 3oz with a full mag. Much better for the use I have planned for it.
