Building or refreshing an AR-15 upper usually comes down to the same handful of small parts, and this Tapco kit rounds them up so you're not hunting for pins and springs one at a time. It covers the forward assist and the ejection port door in a single package, which is exactly what you want when you're working with a stripped upper or replacing worn hardware on an older rifle. The pieces are made from quality steel and finished to shrug off wear, so they'll keep doing their job long after the build is done.
This is a seven-piece set. You get the forward assist plunger, its spring, and the roll pin that holds it in place, plus the ejection port door (dust cover), the door spring, the hinge pin, and the C-clip that keeps everything retained. That's the full complement of small parts on the front and side of a mil-spec style upper, minus the barrel and rail assembly itself.
Many of the components carry a black phosphate coating, which does two things well: it adds corrosion protection and it holds lubricant a bit better than bare steel. Tapco built these to handle continuous shooting, so the forward assist keeps its positive engagement and the dust cover snaps shut with proper spring tension trip after trip. If you've ever dealt with a mushy dust cover or a forward assist that won't reset, you'll appreciate parts that seat correctly and stay put.
Installing these is a rewarding little project, though the ejection port door with its C-clip can test your patience the first time around. A pair of needle-nose pliers, a roll pin punch, and a padded vise or upper block make quick work of it. Keep in mind the dust cover pin needs to go in before the barrel and rail are mounted, so plan the order of your build accordingly. For anyone assembling a fresh upper or bringing an older AR back to full function, this kit hits the sweet spot of practical and dependable.
It's a seven-piece set covering the two main small-parts assemblies on an AR-15 upper. You get the forward assist, its spring, and roll pin, along with the ejection port door, its spring, the hinge pin, and the retaining C-clip. That's everything needed to complete the forward assist and dust cover on a stripped upper receiver.
Yes, these parts are made to standard AR-15 dimensions and work with typical mil-spec style flat-top and A3 uppers chambered in .223/5.56. As always, dry-fit before final assembly if you're working with a receiver from a less common manufacturer. Fit is straightforward on the vast majority of standard builds.
The dust cover is the trickiest part of any upper build because the small C-clip has to be seated on the hinge pin in a tight space. A pair of needle-nose pliers and a little patience get it done, and it's easiest before the barrel and rail are mounted. Once you've done one, the next goes much faster.
A roll pin punch and small hammer handle the forward assist pin, and needle-nose pliers take care of the ejection port door C-clip. A padded vise or an upper receiver block holds everything steady while you work. Nothing exotic here, just basic gunsmithing hand tools.
