Step 4. Attach forestock to barreled action. Attempt to close the system. Carefully examine where material is blocking which part from closing. Remove material until system can close; bolt release can fully lock and unlock the bolt.
*Note. You may have to modify your receiver on the side of the AR bolt catch, adding a 45 degree grind, approx 2mm in depth so that the bolt catch can go all the way up and lock the bolt with a good amount of contact against the bolt face
Step 5. once your ILS is closing and bolt catch operational, remove material from the magazine well of the receiver, carefully checking fitting with a magazine. Remove just enough material for the magazine to click with little to no extra head room for the magazine to travel much past its catch. when removing material near the barrel side go very slowly, to make sure there is metal to prevent the mag from trying to rotate forward. this can cause a feed ramp failure, if in doubt remove material from the back of the magazine well first and take as little as necessary from the front for the magazine to work.
Step 6. Modify Bolt with “Drop Free Bolt Mod” removing the lower rim of your bolt, you will also need to extend the channel further back 1/8-1/4” until bolt seats fully with magazine in rifle.
