Well after having a Slide Fire AR-15, I thought it was time to get a Slide Fire kit for the 10/22. Out of 8 bx-25 mags, 7 of them have failed me in feeding. One mag worked great. And the rest would not load the first, second, third round into to chainber. I thought it might be the kit causing the feeding issues, but the 7 mags bx-25 mags would not feed into the 10/22 takedown I had either. I ran federal champion. Guess I will try another brand of ammo to see it the mags except other ammo.
