As the owner of an actual pushpin gun myself I give you high marks for the decision. Very nice rifle and I will be curious to know how it runs on auto with the 22 kit.
A fellow here in Texas makes a thread adapter that I use on mine which allows the use of 1/2 by 28 accessories and lets me use my 22 Gemtech can on the 308 when shooting 22. Great when doing drills.
We're (Talon Arms) here in Houston so let us know if you would like us to help with the transfer from AZ.
