Perfect Kit
The absolute best kit, I opted in getting all my lower parts separate for customizability (Bolt catch, Magazine catch, FCG, etc.) And this ended up being all I needed. No more, no less. Couldn’t find another kit like this one. Other than that, quality parts.
Exactly what I needed
Arrived quickly. Nicely packaged. Used to assemble Aero lower with upgraded parts. Came with small plastic container that will be handy for storage. Should’ve bought two! There’s always the next order…
Pros:
- performance
- Packaging
Cons:
- None
Best Used for:
- Assembling AR-15 lowers
- extras
Would recommend: Yes
New AR-9 Build
I recently started building my wife her own AR. And I knew that this was the first place to start. I bought all the individual parts INCLUDING all the springs, detente and plungers. I’m glad that 2a put this bundle together and I’m glad the OpticsPlanet was the one who sold em. I had issues with OP in the past so it was a leap of faith that they stepped up their game. And I’m glad to say I couldn’t be happier.
Would recommend: Yes
Fair priced but every thing you may need
Bought a preban colt a2. Hade wobble and noticed the rear detent spring was missing . rear spacer was missing also. I only used one spring. keeped every thing else for spares. I know I do what the guy be for me did , loose it during cleaning .Simple and it fits and works. Can't ask for any more out something so simple

- None
