Yeah it's solid, it's steel and isn't going to slop around. The only slight issue I had with one wasn't its fault - I had a thick sling swivel that wouldn't let an ACS stock lock in the short position but I swapped out for a thinner swivel that did. Oddly the thick swivel worked with a CTR. All four of my lowers have the Noveske end plate.
The biggest issue with assembling an AR isn't so much getting the parts together right - it's getting the right parts together.
