Easy Upgrade--Love It!

This is a well made unit--easy as pie to install--real improvement!!!


Big improvement

I had a difficult time with the spring the first time. I didn't seat it correctly. Ended up removing the magazine holder. Finally got it right. Definitely worth it!


CZ 452 extended mag release

Great product! easy to install and works great.


Genius, Sheer Genius!

M-CARBO must have read my mind. The only thing I absolutely disliked about my CZ-455 and CZ-457 rifles were the cheap, tiny magazine release catch. Cruised the web and there the solution was. I especially appreciated the install videos. Put 2 of them in - took less than 30 minutes total and was an instant success. Great job M-CARBO


Great addition

Having a aftermarket chassis for my CZ455 the stock mag release was pretty recessed in my McRees chassis so shooting NRL22 matches being able to make quick mag changes or even effectively clearing the rifle after the stage the MCarbo mag release is,a Nicely machined addition that s easy to install and a must add upgrade
