Me? I tried to go cheap and bought a DSA mid length upper and put UTG rails on it. Yeah, I learned.

Oof. That's a rough one.

When I got my Smith M&P15 a few years ago, I was doing my research before shooting and heard you had to oil the bolt. So for the first couple of range trips I just gave the bolt a light spray of Remoil. Didnt have a malfunction but I have since learned about what running it wet means.

I mounted a scope to the carry handle.

[M&P15T]

I painted mine....poorly.

While I like the FDE look, unless I sent my rifle away and had it professionally painted (cerakote or something like that), painting it with Krylon's gun paints didn't last very long. The final finish is just too soft.

Then I had to strip it back to black.

Joint Force Enterprises is receiving my Stealth after I finish swapping out a few pieces to have it done in FDE. They do awesome work at a great price if anyone else is looking.

My first rifle was my first complete build and I was way under equipped in the tool department to do it. Took a lot longer and I scuffed the entire rifle pretty well but now I can do pretty much anything to a rifle outside of machining.

I bought a Bushmaster

Actually, I'm happy with my purchase. It's been a great rifle.

[fnfalman]

Bought an Olympic Arms XM-15 because it was cheap.

[engineer151515]

Bought a cheapie free float handguard with rails.
(Brand to remain anonymous)
Scarred up the handrails on the install
Painted the upper to hide the handrail scars - that looked like crap
Then broke the cheapie free-float handrails while tightening up the assembly.

Jez... Sometimes it is just best to take things away from me.

Well - at least the lower is untouched.
I've had my eye on a Spikes complete upper assembly that will erase the problem . . but not the memory..

made the mistake of thinking that $10 used GI mags were as good as new ones

[boomhower]

None that I've found so far. Lots of research before buying and when buying, buy quality stuff. Only thing close to a mistake is I bought a Magpul BAD I didn't end up needing.(Thought the mag coupler wouldn't leave enough clearance but it did.) I bought it used and sold it to a coworker for the same I paid for it so it was a wash.

[MrMurphy]

I didn't.

[MadMonkey]

Shot a rear takedown pin spring across the room when I was building one

[cciman]

some:

Pulled too hard on take down pins, past the stop (either/both)

Dis assembling the extractor and spring, before really needing to. PIA to put it back together.

Let a Wolf round sit inside a hot chamber, before firing. (casing polymer cokes and shell is stuck inside the bore - only happens in AR type guns, never happened inside a AK/SKS type weapon).

Using a auto spanner wrench on a castle nut-- poor purchase = bad scratch. That MFB was tight, even the with dedicated AR tool, I had to stand on the receiver to turn it. Use a good quality tool or you will break it.

Other mistakes pending.

[cciman]

What's wrong with that?

I love my DSA mid with the UTG upper. I did put ladder covers, because the rubbers are too thick.

Nothing that a BCM upper and DD rails didnt fix.

LOL, thats awesome.

I did a lot of reading before making my first purchase. My mistakes came later when I tried to skimp on the optic for my second AR.

[PlayboyPenguin]

The only real mistakes I have made with AR's is buying stock. I should have built my own from the beginning. After one complete build and another total overhaul of another one I could have saved money building them myself from the get go.

[faawrenchbndr]

Cheap optics that did not last long.

[Randy from Kansas]

I did not purchase enough ammo, in 01 I took my new colt out with only 150rds a friend and my son came along we were out of ammo in just a couple of minutes.

Done that.

[sigman69]

years ago buying an Olympic AR15 that was junk...just didnt shoot well, and didnt shoot at all even more!!!!

[daddysnapmuffins]

During the election fiasco when Pmags where impossible to find I bought a Thermold mag which I don't like. Haven't had a misfeed it just doesn't seat as cleanly and takes an extra smack. I also sometimes wish I bought my Grip Pod and rail covers in black. Other times I'm fine with the FDE.

[mixflip]

Just before Obama won the election I bought a DPMS because it was the only rifle left on the shelf.

Btw...it shot fine and never fell apart or broke even though the internet said it would.

[jadams951]

Took out buffer and spring and forget to put it back it in then ripped the CH back and got that bolt carrier stuck pretty bad.
