80% lower Question

[jerrymrc]

I can say that there are other methods of protecting the aluminum but many know that the small area of the pin holes is prone to wear. I can also say that anodizing varies widely between MFG's. in Cerakote work your not looking to remove the anodizing only etch it for a good bond. There have been a couple of items that you could say "Annnnnd, its gone" before you blinked. And jkoby27. Do all us staff a favor and relax.

So, how many rounds does it take for one to wallow out?

How many have you seen wallowed out?

Not trying to pick on you, but you are invested in people NOT doing 80% lowers (lets be honest, you are involved in a store that does a lot of business selling stripped lowers or completed rifles), and you don't give any actual information in your post. You just say it won't work out that well.

You would initially think that, but not really. We are invested in selling parts. The more people who do 80% lowers, the more parts we sell. We have a complete shit profit margin on lowers, and they are only $100-$130 for a mil-spec good one from a reputable manufacturer. We don't even charge for background checks on them. I wished to god there was a way everyone could make their own and do an anodized finish for the same a regular lower costs. We would double if not triple our sales and even sell them. Sadly, it isn't so and we won't recommend or sell shit parts.

Lowers come a few types of aluminum's and production methods. 80% lowers use softer aluminums like 6061 or billet 7075. Both are used to help stop bits from drifting and chattering in whatever the home finisher is using to cut out the pockets and drill the holes. Forged 7075-T6 lowers (mil-spec) would be too hard for any mass marketed process to the average guy to complete without lots of machining problems. Additionally, ALL aluminum lowers are surface hardened through finishing treatment, usually anodizing. Even with the surface hardening, the trigger and hammer holes and the safety selector holes gets repeatedly galled by the steel pins and lever. Even the mil-spec lowers eventually have problems with the holes wobbling out. It takes a lot of use on the mil-spec lowers, but it's simply entropy. Now, toss in a softer aluminum and no surface coating and you have very fast destruction. I've seen 80% lowers with this problem in a thousand rounds. So you add KNS pins, great. It gets you another couple thousand rounds down the road. Now the holes are so sloppy, the hammer is starting to pinch into the BCG and other issues like slip off the sear or the safety doesn't engage tight enough to work. I've discussed this before in at least one other thread other than this. So far I've seen about a dozen with these issues. They are the ones that are getting shot and not collecting dust in a closet somewhere. I've seen about he same that were flat out milled wrong or finished wrong or even both. .5-1 millimeters off and you have a nice expensive paperweight. I hate seeing the look on guy's faces when they bring in a terminal mess.

If it's not a rifle, no stamp. If it is, stamp required. He could throw a 7" bbl on it, and if it was unmachined, and therefore couldn't have a FCG added, no fowl.

BUT!!! If he has an SBR upper, and a functioning AR lower aside from the display, and no SBR lower, constructive intent would bite him in the ass since he could easily swap the upper to another lower and have an SBR.

NOW, if the upper was likewise non functional, could be legal again.

I would likely not use a real barrel. Probably just something from solid bar stock. I hadn't even thought about a fake SBR. I guess if it isn't going to be real or functional then why not make it look cool?

Perhaps I should start a thread looking for junk parts and see if I could throw it together cheap.

Oh, and am I the only one who is wondering why J referred to birds?

Just trying to get him to back up his assertions that 80% lowers don't work, since they actually do.

I'll grab pics on the next one I see and post them for you. They will work until the holes are terminal. Some of us shoot our guns. A safe queen AR 80% lower will last one a life time. Give it to someone dumping 20k round a year out of it and it's virtually worthless.

You know I seen a thousand or so AR's in the last year, right? lol.... Who do you think they take almost every one that doesn't run in the Denver area? Don't even get Firemoth started on these. He's been dealing with them since they first came out. This isn't new information, and it's not my opinion exclusively either. You don't have to believe me at all. You just have to shoot yours more often.

Samsung did that. I assure you. It actually corrected to waterfowl before I edited and didn't notice. It's because I've been texting everyone how good the duck and goose hunting is gonna be at my hunting spots this year... it just learned waterfowl for every thing that sounded anything like the phrase.

No, not really. Good call ray. I done effed up.

Ah, good, you know my shooting habits. Well done, sir, I applaud you... Omniscience must be nice... It'd certainly make the stock market or lottery easier.


Nevermind... You have your opinion and information, and I have mine...

I'm going to go shoot my 3 rounds for the year.
