Thought i would post how easy it was to add an arca plate to my factory tikka stock. I bought the mini plate from Salmon River Solutions. My rifle was bought new around 2017 and had an extra mounting spot for a swivel stud a little forward of the mag well. It had a screw filling the hole that is threaded for a metric m5x.8 screw. I used this as 1 mounting point and then only had to drill 1 hole for the second screw. I bought 1 M5x.8 x 25mm stainless pan head screw with a stainless washer for the existing insert that was there and used an M5x.8x20mm stainless screw, washer, m5 nylon lock nut and a 3/16 stainless fender was shaped to fit in between the channels of the stock. Probably took me 10 minutes to install it all. This could all be done with minimal tools and if anyone is having concerns about installing one of these hopefully this helps.
