Jin's Review of Aero Precision AR15 Upper Parts Kit w/ Ejection Port

Initially I couldn't find the forward assist roll pin... it was hiding in the ejection port spring [clever girl].

The finish on the ejection port was uneven, not a huge deal.

Everything functions and went together smoothly.

If possible install the dust cover rod before you install your barrel nut. Mainly because you don't have to deal with the stupid c-clip. If you're like me and forget that step... you can install it from the back side. Just cover potential wear areas with electrical tape [namely under the forward assist]. Get it started and a few taps with a punch and hammer and it will eventually work it's way down far enough. Use a dab of grease to hold the clip in place and then I just press it down with a punch to set it.

When installing the forward assist, get everything lined up correctly... use a punch from the underside to act as a slave pin. I suggest using a roll pin starter... but if you don't have one then a dab of grease combined with a larger diameter punch will get the roll pin started. Once it's close to flush you can go in with an appropriate sized punch as to not mar your receiver and also drive the pin the rest of the way in.
