Yeah, but you don't even need an 80%, Tool :P

Probably. Edit: foot in mouth, wrong link <lmao>

This guy's got it! Do it, cuz 'Murrica <lmao> So the polymer pistol lowers hold up well? Edit: 80% lowers are good because, believe it or not, most of us don't have access to CADD or CNC

Really, any experience with polymer lowers, 80% or otherwise, will work :)

The polymer lower has been out for a while now, and it's come a long way since. I wanted to get an 80% just to practice up before I go to an aluminum one, but it'll still see a good bit of use. I was wondering, can anyone speak on the strength and endurance of polymer lowers? I'm sticking with 5.56 or smaller, about how many rounda can I expect to run before I've got a broken piece of plastic?

Great post, Tom. This should probably be pinned, I've seen so much confusion on the topic.

It is, you just missed A LOT, GRA. Nothing against, you brother :)

Even if you just go on the link and completely ignore EVERYTHING else, there are way cheaper places to find the same rifles. Even gunbroker has at least two Oracles for $100 cheaper than the lowest on the link. That was just the first result on google, chances are you'll find better stuff out there. Just saying....

Good point, I think I got a little ahead of myself on this one. I probably won't need a heavier buffer on my .308, but I could probably benefit from heavier buffers in my 5.56's with non-adjustable gas blocks. Looks like this one's going to the side for the time being

How have I missed this thread? First and foremost, +1k for Toolndie. Brian cut me a custom barrel nut wrench for my Matrix Aero barrel but. Amazing craftsmanship, great communication, and quick work. Did I mention he does AMAZING work? I hope to put a couple thousand rounds downrange with him one of these days... +1 for Slash (Clint) and HeavyBuffers.com, they did the research and development to make a quality product (even though all I got was a buffer spring :) ) +1 for Mi-Tech Metals (not technically a forum member, but worth a mention). I ordered some tungsten weights for my buffer, but I had problems with identity theft and my accounts were all frozen the day my order was placed. I contacted them to let them know what was going on, and they were very helpful and understanding, and held my order until I could make my payment. This is a company that you have a minimum order price to order anything, and they treated me like a big contract, if you want to BUILD a heavy buffer, or just need to balance a crankshaft, Mi-Tech Metals is the place to go!

Well, Slash's heavy rifle buffer weighs about 10 oz. I'd like to cut down recoil as much as possible, or at least lengthen the impulse to make it feel lighter, since most of my shooting with this rifle will be from a bench. I'll be running an adj. gas block, too, so I figured if I kept my weight around the same as Slash's I could avoid short stroking issues (or turning it into a single shot) without having an overgassed rifle. I figured you used the spacers between the weights, but I meant where in the buffer did you position the heavier tungsten? I was thinking the back of the buffer (plug end) would be a good spot for them, but as long as I use those spacers does it even matter?

Not yet.... Apparently I've got a lot to catch up on.

Does it count if he yelled it on impact? <lmao>

Dude, when it comes to "misplacing" schit, I'm a professional. Doesn't help that my house looks like Jerry's shop on Shootout Ln....

I was actually thinking about taking something and smoothing out the groove. Maybe like a little soldering iron or a really hot needle?

Just got my tungsten in the mail today, so it's about time to add some weight. Hey Wash, how did you position your weights when you added the heavier ones? I took all my measurements to .01 grams, so I'm about to do the math, but I'm going to try and end up with 8.5 to 10.5 oz.

Sorry it took a minute, had to get permission: You can see on the top of the lower the gas key shaped rectangle starting to wear through the anodized layer, and the gas key itself has matching wear. It shows up so much better with the flashlight, but the glare makes it worse than it is. Needless to say, my buddy was pretty embarrassed, but he was glad I caught it when I did. Just goes to show, even a Marine makes mistakes (though some may not admit it)

10-4, Major :) Buffer (and spring to be safe) on the way. Pics tomorrow, probably. Phone's about to die

I know to drill before I tap, I don't want to break it off on my first time :D I just meant I don't have a 4-40 tap, I've got 50 years of random bits from like 4 generations of mechanics and machinists. Where's my smiley bar when I need it....

In my defense, it was done at 4am at the end of a 2 week stint of working 3-1 every night with a Kobalt box cutter. Got that schit to work, though XD

I honestly didn't even think about opening the hole up for a bigger stud (wait for it....) I'll probably go 6-32, I know I've got that little baby tap, at least. For now, though, my coat hanger mod looks to do the job, as it just happens to slide right in with a light coat of grease with no sideways play and just enough spring tension

Friggin' Photobucket, man, breaking all my links:

It looks schitty right now, I just wanted to make it fit at the moment. I'll go back over it and smooth it out later.

I just noticed the top of the face of the lower where the ext. mounts the anodizing is starting to show signs of wear. The back of the gas key has a light silver line of wear, which makes me think the gas key was impacting the receiver. The rifle has a full auto bcg, which may be why there isn't any real damage, or even signs. The wear is so tiny I had to take a second look when you posted to see anything, farkle I just don't understand how he didn't have any problems. I mean, dude is a Marine who works with guns all day, so it seems like he would notice something not feeling right. Easy fix, I just need a rifle length buffer, I was just thinking, if it ran fine with the carbine buffer, would the .308 rifle buffer be safer (or at least enough to test fire without doing any damage)?

A buddy of mine brought me his PSA PA-15 today. He switched out the carbine stock with an A2 a while ago. He said he ran 300 RDS through it the other day with no hiccups, so I figured I'd clean it up a little bit. I noticed the face of the buffer right away, with that nice black finish and PSA insignia, so I decided to pop her out and take a better look. Lo and behold, it's running with a carbine buffer. I called buddy and he said he replaced the buffer tube and spring, but left the buffer. Now he said it ran fine with it, but I still feel kinda funny about it. I know you can't run an AR-15 buffer in a .308 due to the .223 buffer being longer, but will a .308 rifle length buffer work in an AR-15? I just happen to have a spare .308 buffer, and I think it's only like 1/5 oz heavier.
