I have been waiting for over 4 years to get my new PMR30, which I finally purchased recently. I have been watching M*Carbo on YouTube for close to 2 years. Over a year ago I turned my friend on to M*Carbo; specifically the PMR30 Full Upgrade Kit. My friend was TOTALLY blown away with the performance this upgrade added. So I knew I HAD to have this upgrade day 1. Ordered the newest Full Upgrade Kit at the same time I purchased my firearm. Installed everything as soon as it arrived!!! To quote Chris Nelson: "I have yet to do a PMR30 mag dump and NOT smile.". Superb perfomance! FAST shipping! Quality parts! I WILL be back for more! Thank you M*Carbo!!!
