I have a pair of them and LOVE them. Trigger pull is comparable to my two IBM M1 carbines. I did have to file down the front sight to get it sighted in correctly. They do slip right into the repro M1A1icon paratrooper stock that you can get from Numerich.
Here is a link to my thread about them in the .22 smallbore section, also a pic to wet your appetite.

The wait begins!
