USPerfect kit
Everything was included that I needed. And every part worked right out of the bag. Super happy with this upper parts kit.
USBetter than I thought it would be
I was impressed with the NBS after market slide completion kit. It's quality was on par with most other after market basic level kits, but the cost was significantly less. While this is not an OEM Glock kit or an expensive upgrade, it fit and was serviceable. Great bang (hee hee hee)for your buck! Manic Mike
