Airsoft Canada - View Single Post - Firepoint RDS melt in! I finally finished something.

I finally go around to doing some work on my own collection. I haven't finished a project in awhile.

This time, I did a "melt-in" installation of a Firepoint RDS. The melt in installation sinks the RDS into the slide such that you can see the slide thru the RDS while acquiring the dot. It seems that aligning the gun such that the dot appears in the RDS window is quite instinctive as you naturally line up the top of the slide and the front sight pretty quick. The dot comes into view pretty quick and gives you a lot of extra viewing angle over having to line up the iron sights.

The slide is a Kimber aftermarket metal slide on a TM 5.1" Hicapa. I went with black as I prefer muted tones to race gun shine. Maybe I'll do a race gun someday. For now, I prefer stuff that is just business.

The surface for the RDS is milled down about 4mm at a 1deg downwards angle. The downwards angle is duplicated from a mounting plate which is meant to be used with a non melt in installation. I didn't want to use the mounting plate as I wanted to get the sight as low as possible so I milled the slide at the same angle.

I wish I could have mounted the sight a bit further forward so the back end of the sight didn't hang off of the rear of the slide, but there isn't much meat to tap screws into ahead of where I put the mounting screws in. There's also a blowback mechanism inside which I had to modify to clear the bottom of the sight sunk into the slide. The rear area where the stock bomar fits was filled in with JB weld before machining the mounting surface. I used aluminum tape to follow the contours of the slide and make a shaped pocket to inject JB weld into so the cast shape matched the cross section of the slide. The shape was razor cut while the JB was still soft to save on sanding and finally filed to final shape after hardening.

I just got a sewing machine so I can mod my holster to holster this gun with the sight on.

The trigger is shortened to about 2.5mm pull for supah trigger action.
