Awesome company
Kits came as advertised, no problems. I also ordered a half dozen roll pins and received seven. Good looking out for guys who lose parts! Y’all are my go to company for parts.
Oops Kits
Purchase for spare parts. You’ll be surprise just how useful having spare is when you open your AR and the springs go a flying. Recommend to everyone who owns an AR, sooner or later your going to need these parts.
Great purchase
Got exactly what I needed in the kit. Shipping was not bad with all shipping delays in the country now. I find these guys to be on top of their game and buying more from them.
Best idea ever
The oops kit is awesome. I lost one spring and paid more for the one spring than the entire oops kit, so glad I found this!
A must have for every builder.
helped me finish a build in a pinch. great to have spares
Just what I needed.
Didn’t need an entire lower parts kit.. just a few springs and pins. This kit worked perfectly.
Must have!
Absolutely must have for the range bag. You never know when you'll need a part on the go.
Exactly what was Needed
Has all that gets lost or damaged.
Should be in everyone’s toolbox!
This is a great idea. “Oops” is not the exact word I used when I dropped my selector detent in the carpet BUT you get the idea. I recommend having at least one of these in your kit!
Great little bit of insurance.
Hopefully i never need anything, but of i do i know the whole kit costs less than just the buffer retainer in the town i live in. I know this because i had to buy one and i think my local caring gun store got me for 20 bucks!
Detent failure
Bailed me out when I broke a detent spring.
Just what I needed
This Aero Precision Oops Kit is perfect. Who doesn’t have a spring go flying across the room while building or working on their AR-15. Carpet, rugs, or hardwood floor!!! It doesn’t matter where it goes flying your never find it!!! Why bother looking when you have this Oops Kit for easy replacement. Thanks!!!
Not as described
The listing says it includes the following in it: Includes: Takedown Pin Detent (4) Takedown Pin Spring (4) Bolt Catch Roll Pin (2) Trigger/Hammer Pin (2) Safety Selector Spring (2) Safety Selector Detent (2) Buffer Retainer (2) Buffer Retainer Spring (2) Disconnector Spring (2) 4-40 Set Screw (for threaded takedown pin detent hole) (2) Threaded Roll Pin The problem… read more is that other than the 2 detent springs, 2 detent pins, you only get “1” of everything else. That’s right “1”, not “2” like the listing says you get. On top of that, this product is supposed to be an Aero Precision Product, but it’s just a bunch of springs and pins dropped into 2-3 little baggies. Everything I have ever purchased from Aero Precision comes in Aero Precision packaging and includes and Aero Precision Decal. Would I recommend this, site but buy it from Aero Precision so you know what you’re getting.
Very Good
All of the parts were exactly what I needed. Thank you so much!!!
Consistent
Just like the original. Great for maintenance..
THIS IS GREAT
LOVE IT! ORDERING MORE KITS.
Necessary
comes with ALL the parts you just lost. ;)
Great kit as always aero precision quality is great, fast shipping from AR.

Great product
I ordered 2 oops! kits and they arrived within 4 days. Great service.
Great optic
This is a good optic. Turrets were a bit tight at first that I thought they were stuck. They are just fine now after clicking a few times. Good price as well.
Oops kit.
Great kit to have or finish off builds.
Convenient fix-it kit.
Like many others, I've lost springs and detent pins, especially when I was new to assembling a lower. I appreciate that the kit contains an excess of spare parts, and you can count on Aero Precision's quality.
Oops Kit Eases Frustration
The Oops Kit includes those essential items that often get flung across the garage and lost seemingly forever while performing a lower build. The Aero Precision pins, springs, detents, and retainers are of good quality and fit well in both of my recent lower builds. For the price and quality of the parts, this kit can not be beat. Ease your frustration caused by lost/ejected parts… read more by having these extra small parts on hand for your next build or retro-fit.
Oops kot
If you’re building ar’s this kit is essential. The cost is low and shipping was fast.
Springs and detent kit
Great kit and inexpensive. I consider it a must have. Little parts are easy to lose so it not a bad idea to have extra. Great quality...
Handy to have around
Very useful product and well priced
You'll need this unless you
When you say "oops" because your detent spring just disappeared into the distance, just reach in here and get the replacement!
Love you guys
You are my go to e store for gun parts
First time with them
great no problems at all and the little problem I did have was my fault and they caught it before shipping very satisfied
Ar parts
Came fast just what I needs for a quick repair
Pins anyone?
I don’t know how many of the tiny detent pins are scattered around my gun room. It’s so easy to slip up and have the pin shoot off never to be seen again. A few extra around is a great idea. This kit is a must.
Must have
A must need for a build or tear down, Stupid pins!
Keeps you throwing lead down range
Needed some more spare parts for the range box. Everything you may need in the field for a quick fix is in there. Good to go.
Great parts fast shipping
Fit great , price was great , shipping was fast
Aero Precision Oops Kit
For the inevitable oops when you launch a detent spring into the abyss.
Thank goodness
I bought a detent that was sent into the netherrelm at mach 7 and 2 oops kits just in case.
Great value
Excellent....when you lower comes with almost everything....oops kit is perfect
Every AR owner needs a few of these
Only kit that comes with the 4-40 set screw plus everything else that flies off into space never to be seen again.
Opps kit
Product is perfect. Shipping is quick, just as described. Would recommend for anyone building a kit or need extra parts!
Every one should have this.
A must for everyone who builds or fixes guns. Excellent.
Great for small parts you might lose
This is a great kit for small parts that might shoot across the room while installing. Detent springs are notorious for shooting across the room on install. This is also a good kit to have if you plan on building a lower with custom parts and don't want to buy a full lower parts kit as you'll be replacing some things.
Awesome Kit
I love this kit for the quality of the parts. The price is second to none for the amount of parts included in the kit.
Buy it!!
Very helpful on my PSA build.
Oops I found them all
Literally every oops I lost it....found here!
Small parts
This is a great kit to have on hand. Sometimes we slip and , oh shoot there goes a spring. Quality replacement parts.
Oops kit
Great product. As is described
