I imagine many on here saw my post on OMR - Oregon Mountain Rifles and the bad experience I had. One of the big issues I had with the semi custom gun that he built was that it had significant feeding issues. Unfortunately the owner of OMR had zero desire to try and make things right, but the guys and gals at AG composites, specifically Matt and Pam, were awesome throughout the process. In the end, I was able to make my stock work by milling out the inlet a little more and sanding down my bottom plastic. It wasn’t ideal and it wasn’t what I wanted, but at least my tikka wasn’t a single shot!
I sent Matt and Pam a lot of pictures and videos and I was told they were working on a new mold, a gen 2 stock. Last month they sent me a foam stock to check the barrel channel and it looked like a perfect fit. Today the box showed up with the real deal!
FINISH - no different than the gen 1. Everything is perfect. The paint is sharp, the edges are smooth, there are no blemishes, no rough spots, nothing unsightly. The barrel channel is even all the way down with excellent clearance for a free float. It looks fantastic!
GEN 2 TWEAKS - this is the big part. One of the main issues with the gen 1 was the thread engagement on the bolts. I could get about 2 full rotations, and some guys complained they couldn’t even get that much. The gen 2 gave me 4.5-5 full rotations of the screw driver on both the front and rear bolts.
The gen 2 is on the top of each picture below, you can see how much more bolt it sticking out after thread engagement.
The other issues, and the big one for me was the depth of the stock at the magazine well. This caused the magazine to seat farther from the action and didn’t allow the bolt to grab the cartridge reliably. It’s hard to explain but pictures are worth a 1000 words. The picture below shows the depth of the stock, from action to mag well. As you can see the gen 2 is about .1” shallower than the gen 1.
In the pictures below you can see the red circle shows the gen 2 seats the magazine up against the action where the gen 1 had a gap. By moving the magazine up against the bottom of the action, the bolt was able to “grab” more of the rim of the cartridge, making for 100% reliability in my testing.
I ran both the tikka factory magazine and the latest generation mountain tactical. In my old stock the tikka mag was about 90% and the mountain tactical was about 20% feed reliability. I ran both multiple times and both were 100 reliable.
