Sig 522 mod
This is the first Sig Sauer weapon I bought. I was impressed with the info on it, and made just a few modification to the .22 rifle.
I took out the faux gas asjustment plug. That was there to store stuff. My pockets do just fine. What I did was take off the front sight block. Drill and tap for a set screw 8-32 allend head, and attched a laser I bought from Wal-Mart for under $50.00. I wound the on/off swich cord though the handguard vents to be on the left side for activation by my thumb. The set screws allowed the laser to be mounted far enough out to access the laser's external adjustments for elevation and windage. The laser uses a larger flat head screw to tighten up the mechanism to the chassis(laser) and I had to loosen it slightly to get the laser to move, and then re-tighten. It was kind of a ***** getting the laser to point where it was hitting as even though I moved the adjustment set screws on the laser housing itself, when I tightened up the locking screw it moved it just a bit. Anyway, it provide excellent function to close in shots for the Sig 522. To change batteries, just take off the top hand guard and access the rear of the laser unit.

While were about pictures, below are Safety Lever hightlights I made for myself to see at a glance under low light and you can even fell the "dot" that is exposed when you move the safety lever into the fire position with just your finger. I drilled a small dimple in the spot covered by the safety lever when it is in the "SAFE" position and when the lever is moved into the FIRE position, the red dot now shows and you can also feel it with your fingers, even in the dark of night.
Safety to ON position
Ready to FIRE. You can also see the leftover pencil mark I made to outline where the safety lever position was before moving. I used that to gague where to put the small dimple.
