If you want to remove the mag safety there are several ways.
1. You can just remove the mag safety and add 2 or 3 small 5mm stainless washers on the MKIII bushing.
2. You can order a Clark oversized MKII bushing and use it in the MKIII hammer with a slight visible gap in the hammer that does not affect performance.
3. You can order a special bushing that has a built in shim for use in the MKIII hammer from Sam Lam by email at

4. You can order a Volquartsen MKII speed hammer and MKII bushing.
5. You can order a Majestic Arms MK3.2 speed strip kit that comes with an original style MKII hammer and bushing.
6. You can order a BAM bushing which is a US made copy of a Sam Lam bushing at http://bushing.webs.com/
As far as the LCI filler just contact member bpatza on Rimfire Central and he sells them for about $20.
As far as I know there is no one stop shop for both parts. Ben's LCI thread was removed at Rimfire Central because he was just making the parts as an individual and some of the sponsors there apparently didn't appreciate it. Now you just have to be "in the know" and contact him directly.
