Buffer weight for AR carbine
I am going to get a captive buffer for my AR. It’s a 16” barrel with a carbine length gas system. I am having trouble finding a definitive answer on whether the weight should be 3.3 oz or 3.8 oz.
Which one would you AR guys choose? They are identical in every way except the .5 ounces, cost the same and you are stuck with the weight you buy. It’s Armaspec stealth recoil spring in case you are wondering. My main purpose is to remove the buffer spring retention detent and spring so that a chunk of the detent does not end up in the fcg at a future time. Also I don’t like the sproing sound for what that is worth. Captive buffer springs are also a thing for those running cans, I have no intention to run one unless they are removed from the NSA list. My attitude has already been noted.

Never seen anyone break a buffer detent. Seen a lot of folks shooting M16s on full auto, too.
Sometimes I sure have to wonder about some of the gadgets that come out on the market. But, if that's what floats your boat? I think 4th ID is pretty knowledgeable as to buffer weights and what works best, though. How's that for a non-answer?

Actually I think with a KE Arms SLT-1 trigger I intend to get a sheared detent wouldn’t FUBAR it anyway.

I think if your detent sheared off, then you have bigger problems, anyway - like a buffer tube coming unscrewed. Most folks who build their own don't bother to stake the castle nut, and after a while it can loosen and allow the buffer tube to back out - probably long after they've already forgotten that it could if it isn't staked.

Their are tons of YouTube vids. on buffer springs and what works best for a particular weapon. Now do NOT waste money on buy this brand X buffer at this or that weight. No. $$ Make your own. EABCO Tungsten Buffer Weights fit AR15, 3-Pack https://www.eabco.net/EABCO-Tungsten...k_p_16097.html Their is some their are better prices. Google it. Take a heavy spring light spring heavy buffer light buffer etc. to the range and experiment with your particular weapon. Take your time one WILL work. Pain in the ass but like tuning a car you can do it.

This guy made his own version. The Armaspec is lighter than the JP. I have two of the five gucci lower parts. Going with KE Arms trigger and safety and Teal Blue Bravo’s PDQ holt release. Going to cheap out and get knock off mag release because stock design puts my index finger too far back from mag release. Tried Odin mag release extension but contour of lower does not allow its use for me. Figure I can drop mag with left hand while holding new mag in it. Standard lowers I can reach the mag release on. I bought the GWACS lower because it’s close to indestructible, won’t rust, won’t heat up in the sun (unless it’s black) and it eliminates a lot of small parts. Also when I had functioning shoulders I thought it would make a decent club especially with the brutal aluminum murder/death/kill treaded butplate. The only downside is the distance from back of the pistol grip to the mag release. The buffer assembly is least important to modify in the lower. Not presently modifying/building an upper. https://www.youtube.com/watch?v=HbadL_jewsE&t=3s |

2.66.
I don’t think it’s possible to shear the pin unless the bolt and bolt carrier are to short and I’ve never heard of that happening. If you have the bolt and carrier locked into battery and you watch and feel while you slowly close the receivers you will notice that the carrier actually slightly presses on the buffer right when it closes. I don’t think the buffer puts any pressure on the pin unless the receivers are open. I just weighed my M4 carbine buffer with retracting stock. It’s only 2.66 ounces? |

That Karl turd and one or two other YouTube ninjas insist it happens. I would rather leave it in with the captive buffer spring to keep it in there. This hollow GWACS lower amplifies the sproing sound, it reminds me of the stories of the first hollow stocks on the M16 making a bonging sound when struck on a tree trunk in Vietnam. They were filled with styrofoam afterwards. That is either from TimeLife’s Vietnam experience or Jane’s Infantry Manual 1978. I am pretty sure it was TimeLife that bit came from. The internerd guru Komrade Kasarda showed a photo of the beefed up buffer detent on the H&K 416 as proof of his contention. Sinistral Rifleman Russell Feigan, the guy behind the Cav Arms nylon lower in the first place, has also said he’s seen it. One other YT ahole said it too but I don’t remember who it is right now so I’m obviously FOS and my parents weren’t married. Last edited by Bluntforce; 05-01-2020 at 02:47 PM.

I've got7 or 8 uppers and 5 lowers I've put together with all kinds of parts and they have all worked over the years. Real mis mash guns. I don't plan going to war with them so they don't have to be mil spec, whatever that means. They do everything I expect them to do and I've had very few problems with any of them. Mags are a little different on occasion.
