I am putting together a trainer rifle for my ATX with a short R700 ATX chassis and have hit a wall. The long foreend bridge does not fit the short chassis and the short bridge fits fine but there is no 20MOA rail section for the short bridge. I am running a 20 moa R700 scope base and I want the ability to run a clip on without massive zero shift. EuroOptic does not have any idea either. Short of machining something myself which I'd rather not do I really have no idea what to do. Here is my parts list so far:

AICS R700 Short Upper : 29743FI-DE
Bergara B-14R Barreled Action .22lr
AI 20 MOA Action Rail : 20060
AI AT-X Short Forend Bridge: 29380
AI Full length 10" Rail : 20369 (Does not fit short forend)

(think AI ATX border patrol rifle)

I suppose there are a few options that I've thought of looking at parts. Shorten a full length forend bridge and 20MOA top rail to fit only to lose my forward most mounting screws which I don't want to do due to rigidity. Run a 0MOA base which hinders long range .22 badly and the corresponding 0 MOA rail section on the short bridge. However, the best possible solution would be to find the correct 20MOA section for the short forend if it exists. Any help, advice, or part numbers from someone who has already done this would be so helpful.

Tom, copying my post in the thread I started about 16" barrels and 13" ATX Chassis as it's relevant to your thread too.


My buddy brought over his short chassis ATX for us to mock up some rail situations.

It seems there are no 20 moa top rails that will fit the 13" forend.

The top rail in the picture is off of my 13" AXSA AICS chassis. It would need to be slightly shortened and it also sits about 1/16" lower than the action rail.

Also, just realized they make a medium sized bridge to work with the 13" forend. The short is on there as we thought you would need to chop the long bridge to work.
