Re: AICS 1.5 front block
Just finished installing the short block, and it's a fairly painless task. Here's how I did mine.
1) Remove the action.
2) Remove the skins (the action screws will fall out at this point, as they're retained by the skins).
3) Remove the 2 hex head screws, and drive out the large roll pin holding the long block. The sling/bipod mount will fall out of the bottom once this roll pin is removed.
4) Pull the block slightly forward, and slide the sling mounting plate out from either side.
5) The long block can now be removed.
6) Drive out the small roll pin which holds the release lever and spring into the long block.
NOTE: The small roll pin will have to be shortened, as it has to fit inside the chassis with the short block installed.
7) Install the release lever, spring, and shortened roll pin into the short block.
8) Remove the round rubber spacer from the top of the long block, and install it in the short block.
9) Install the short block in the chassis, and slide the sling mounting plate in from either side.
10) Install the bottom sling/bipod mount, and the large roll pin.
11) Install the action screws, attach the skins, and install the action..
You'll have the 2 screws left over that secured the long block, as they're not used on the short version.
Finally!
