Buffer tube kit and parts
Great parts with fast shipping These are the kind of groups you get when you buy your parts from AR15Discounts.com
USNBS rocks
Parts seem to be really good products, nothing special but definitely seem to be quality stuff at a great price point. Buffer tube has a very nice finish as well as the the buffer and spring. Parts kit has your basic phosphate finish but all the parts look very well machined with no burrs or jagged edges and fit my lowers like you’d expect. My only gripe is AR15Discounts has to have the slowest and worst shipping out there. I’ll still order from them but would be nice to have better shipping options for better service.

Out of the box, you'll be able to notice the material quality. I have a similar parts kit from the other guys but THIS kit is a step above.
