Great price...some small issues - Tactical Superiority AR-10 Lower Parts Kit A2 Black Grip, .308

Great price, but there were some issues:
* The magazine catch release shaft was too short. I believe they sent me one for an AR-15, not an AR-10. Release button wound up flush with receiver body.
* No set screw included for rear take-down pin hole...my lower is threaded, not sure if all are, so not sure what to think about this issue.
* While I think it's a great idea that they put their parts in color-coded baggies, the detent and spring for fire select were switched with rear take down pin detent and spring. This led to a bit of confusion on my part. I have built quite a few AR-15s; this was my first AR-10 build. Not a huge deal, but it did lead to some head scratching for a few minutes.
* Top of pistol grip had a few mould imperfections, which were remedied with box knife. No big deal.

Bottom line: Great price, products seems sturdy, of decent quality. We'll see how it works out in the field.
