I would love a 6" or so 22 bolt gun and the toggle action has always interested me.  Reviews seem to indicate that accuracy isn't any more than 10/22 accuracy and the trigger isn't great (but it takes 10/22 trigger packs).  I don't really care about the quick change barrel of caliber swap.  But I do worry that it is a umarex.  Mostly I am curious if I would be able to relieve the stock to sink a suppressor with a short barrel.

I was interested in the PWS/summit rifle in the past.  the 20 MOA built in the pic rail wouldn't be helpful for my use.  Nor the price tag.  for just the trigger and action of the summit you are at 750 bucks. I would probably end up with a fancy chassis for another 400 bucks and it would quickly spiral outside of the realm of what I want to invest in this project which will already cost me 2 $200 stamps.

EDIT:  Given my recent experience with an FN umarex.  I think this one is off the table.

Pretty cool. I hadn't heard of them. I'd like to try a toggle action out sometime.

I'll have to look more closely at this.  Could it be an inexpensive way to get into a biathalon rifle?

I don't think you can build an accurate rifle with a barrel change system that is closer to an air chuck than a precision system
