Im new here, and still figuring out the navigating details. Anyway, my answer was stareing me rite in the face. I just needed to talk out loud about it. All I needed was an A2 buffer and spring for a 5.56, instead of the one I had on the shelf for a .308. It's fixed now and running just fine. Thanks

I checked all that. Gas block, tube, key and rings. Everything checked out. I also tried a new bcg, then I put the upper on a carbine lower and it ran fine. I also tried a different upper on the A2 lower and it wouldn't feed another round. That's when I took out some buffer weights and tried it with the longer and heavier A2 spring. No luck on either of the uppers. That's when I decided to try the carbine spring, I stretched it out a lil bit, but it all worked fine. I took it back apart and checked for any unusual wear or shiny spots. Everything looks clean. The A2 stock, tube, buffer and spring were originally from an AR-10 .308. Idk if that's the reason for the cycling issues? But I ran 2 full mags thru it just as fast as I could with the 2.8oz A2 buffer and carbine spring. All I know is that it works great now.

Ok, so I put the A2 buffer on the scale 5.4 ozs, then the carbine 2.9 ozs. I lowered the A2 down to 2.8 ozs and still using the heavy A2 spring. Just did a test firing. It will eject the spent shell but won't feed the next round. Hmmm? Bcg maybe? Tried another, no diff. Tried mine in another rifle, worked fine. Then the lil lite bulb in me head come on about spacers! Kudos to Mr Nugget! I started thinking about the spacer idea in order to use a carbine buffer in the A2 stock. Since I reduced the buffer weight on the A2 buffer it dawned on me that it would act as a spacer paired with the carbine spring. I just ran 2 full mags thru it, and except for the smoke cloud it worked just peachy!!!!!!! Lucky for me that I remembered that I had a green 2'x16" thick log of Osage orange out back that I was going to use as an anvil stand but made a different type of stand instead. It's a super hard chunk of wood. Average penetration was 4" deep. Almost 9" with a fmj 300 aac. Thanks to all for reading all my babbles and helping me answer my own questions with your input.

Only with a small nucleus of friends that I shoot with. I'm vetted with our local 3%er's, and militia but I prefer to stay low key, cocked n locked when needed. I've built the majority of the rifles and pistols for the guys I shoot with. Bolt actions and AR's. As they would put it, I'm "The Guy" to call to fix most everything. Lol. It's not that I know everything, just brave enough to take anything apart and see what's under the hood. I'm also one of the oldest and it shows. It ain't the age, it's the mileage. I/we've got custody of 2 toddlers (stepdaughters kids) so I've got the watch most of the time. I'm a stay at home Granpa. So I don't get out to shoot as often as I'd like. Rite now I'm tinkering with a 223 Wylde I've put together from misc spare parts. But instead of using a carbine 6 position buffer, tube and spring, I opted for an old A2 stock for a nostalgic look. The length of pull and feel is perfect for me, but with the heavier buffer (it came out of a .308) and it doesn't want to cycle. I just put it on the scale and it weighs 5.4 ozs compared to a carbine buffer at 2.9 ozs. I pulled out half the weights down to 2.8 ozs, but I've still got the longer and heavier spring in it. I'm not sure if it'll cycle yet, and debating if I should use the lighter spring? What say you???????

Funny you should mention that. Cause that's just what I did. Lol. There must be some great minds out here eh. I sprayed the hell outta it also checked the gas rings. What I should've done was swapped lowers with the blackout I had with me. I didn't think of it till I got home.

American eagle 5.56 is what I was running, but I also roll my own. This has got to be a buffer issue? Everything else is the same same carbines with mid length gas tubes and std gasblocks as my others except for the A2 rifle stock. Although I do use the A2 length tube, spring and buffer on a .308, and a 6.8 spcll. It just all points to the buffer. Tanks

I'm a big fan of the Remington 700 platform. I've built 2 from scratch in .300 win mag. Took out a nice 10pt last season at 438 yrds. It was all so awesome! Having the time to range it out, double check wind value and settle in for it. The part that wasn't so awesome was going to fetch it! Why don't they just try to help out a run towards the truck?????? In 30yrs only 4 have ran towards my truck..... I've also got a couple of tackers on an AR platform. That's why it's so weird for me to be havin issues with something I know has to be simple??????

Uh, I've got a couple 3

I understand the idea of a spacer in order to use a carbine spring and buffer. But what if I used the A2 heavy buffer with the lighter carbine spring? At this time I've got both carbine spring and buffer in a rifle tube. I can definitely tell the difference! Also with the carbine spring I can hear the rattle of the spring in the tube. This I believe is the only reason why this rifle isn't cycling. I've never tried this setup before. Everything else in this build is functioning properly. A spacer would have to be approx 1-1/2" in order to take up the slack of the lighter spring. But what if the problem is the 5oz buffer? Using the heavier A2 full length spring with a 3-4oz buffer, but I think the lighter buffer won't have the mass needed to compress the spring? This has become a bit of a conundrum I think? I was using an 8x8x24" chunk of wood to testfire in my basement, but I've blown it to smitherines. Lol. I'm setting up a safety discharge sand barrel like the ones that were kept on base at building entrances to safely unload a weapon prior to entering. I've got the steel drum, cut out a 10" hole in the center for the muzzle. Now I just gotta get 4-5 bags of sand to fill it with. Then I can do some actual live fire test to make sure we're cycling and or which combination works better? Does anyone know of any other reason why this action isn't cycling? With the A2 spring and buffer the action won't even move to cycle the next round. I've run into all kinds of issues with dozens of builds, just nothing like this. Im open to any and all suggestions. However, I still think it's in the buffer assembly..... tanks everybody for the input. I'm feeling kinda dum at the moment and not liking it at all.

Thanks. That basically depends on the mood I'm in when I go out to my shooting spot. Lately it's been all about long range, but since everything eventually turns into a science project. As in working up different loads, trigger weights, breathing, etc etc. How bout you?

I know there's a difference in length and weight that comes with the A2 buffer tube. I have one in my .308, there's also one paired in my 6.8 spec ll. But for a 5.56 I'm thinking that I need a lighter buffer and spring. I'm using a mid length gas tube, for such a light load as the 5.56 I just don't think there's enough gas pressure to cycle the next round? The other day, I didn't think to swap out lowers with the .300 aac I had with me. Duh. I'm positive that would've fixed my single shot 5.56 issue. I want to keep the A2 stock on it cause the length of pull is perfect for me, and I don't have the rattle of the 6 position. I've probably just answered my own question here. Thanks to thinking out loud with other shooters. Thanks.

Ive just signed on so greetings everybody. I hope this is the rite place for this topic? I was reading a question earlier about the difference between the A-2 buffer and spring, and the carbine length buffer and spring. Yesterday I was out test firing a new .223 Wylde carbine upper matched with an A-2 fixed stock with matching buffer and spring. The results ended in a .223 single shot. Duh. I've got a carbine length buffer, but should I use the buffer and matching spring? Or can I change out just buffers. This is my new hypothesis. Also, for .223, 5.56, and .300 aac overall case length should be 2.060" (+-.003) I've made some subsonic 230 gr lead bullets. My results are not all blackouts have the same headspace. Any takers? Or have I just answered my own question? It happens...... Quote Edit
