Has anyone installed the JP FCG on their 15-22? Since I can't seem to sell the one I removed from my AR I just decided to try it on the 15-22. I would like to know if the pins of the 15-22 will fit the JP FCG. Thanks
The pins are the same .154" diameter as a regular AR, they are just a little longer to fit the wider receiver of the 15-22. If your AR was a Colt, with the larger .168" pins, the FCG will not fit the 16-22.
