Thumbs Up KMP RHSP and trigger parts came in today!!!

Picked up my KMP RHSP and trigger parts from my FFL today, Im excited to get started on the build! I have been looking over the M3 top plate and the bracket assembly, and I think I have it figured out, where I need to modify the M3 bracket to get the new trigger parts to fit. As good a place as any to get started. As I make cuts and modify the parts I will post photos.

Thumbs Up Milled out the M3 Top Plate Bracket

Milled the M3 top plate bracket to hold the KMP trigger bar/disconnector assembly. There was a lot of material to remove so I took my time and made a lot of lite cuts. A carbide end mill is a must. The only photo I was able to find of a M3 top plate bracket modified for the KMP parts was from Toolbox82, Thank you!!, that helped me figure out what needed to be cut to get the trigger bar/disconnector assy. to fit. Next I need to make a small block to fill the cut in the rear lug of the bracket, and fit and weld into place the full auto trigger block.

Looking good. My bracket came machined so I just had to weld on the bar do a little dremel work to fit.
Just a note for later if you are using a M3 buffer/spade grip assy you won't be able to install it on the gun with the trigger pin installed. Your buffer will hang up on the trigger. When you are completely done you can file and grind the trigger very carefully so it will clear, recreate the bevel so you keep a smooth trigger pull.
Good luck and keep us posted of your progress.
Greg

Mrgreen M3 build update, welded in the auto trigger block &

Welded in the auto trigger bar block and made a filler block for the bracket lug that was cut to get the KMP semi-auto trigger/disconnector to install. Then I did a fit check to see that the cocking leaver has clearance and the bolt goes into battery. So far so good.

You will be glad you upgraded to KMP.

But now you will be broke, this weapon is hungry and feeding it is expensive.

So far I have no complaints with the parts I got from KMP, very nice quality. Im doing the initial fit check of the RHSP, and it looks good, so Im gonna start drilling it out.

Unfortunately she is going to be on a very lean diet for a while.

Looks like you got a good hand on it. I found that it was very handy to use the M3 tripod ( as you are ) while fitting and testing fitment of parts at all stages. Keep up the good work and love the pictures
