    This thing shoots bulk 22lr with less malfunctions than a Ruger 10/22.

    Stuck in receiver

    Posted by Ralph Escriva on 31st Mar 2021

    Conversion shoots fine, no jams in first 100 rounds or so. But it consistently gets stuck in the receiver and is very hard to remove. It seems like its the part that goes into the chamber that gets stuck - I have to push on the conversion kit with a pin punch to get it out. Actually broke/bent two pin punches and had to use a higher thickness one to finally get it out. It gets stuck pretty much every time I put in the conversion - even happens before I ever fired it, so it's not due to expansion due to heat.

    At first I was skeptical, after running over 1000 rounds I can say that I'm impressed. Not a single Jam. I LOVE it. BOTACH great Customer Services and fast shipment.

    Great kit

    Posted by Steve on 29th Sep 2020

    This drop in conversion is perfect for a cheaper ammo option and allows you to use your standard rifle. All magazines ran flawlessly and fit in normal mag carriers. The bolt cycled fine with all kinds of ammo.

    Flawless Operation!

    Posted by Perry Fernandez on 23rd Jun 2018

    Works every time! I used Federal match bulk ammo as well as other brands. Be sure that you have rounded hammer for your AR-15 instead of the notched type. You can easily tell if you open your AR and look. I had to replace my hammer to the round one. If you shoot with the notched one, you'll experience many cycling problems.
