[ARCHIVED THREAD] - Recoil reducing rubber buffer tips (Page 4 of 7)
|
Here is the one inch silicone bumper I bought on Amazon for isolating audio equipment from vibration. I screwed it onto the end of a Tubbs Flat Wire Spring. It is fairly soft, springy material. Doesn't add to the length of the spring very much so bho may still work. Should stay put since it is in there tight.
Have no idea how a springy bumper like this at the bottom of the tube will work. I'll try it with a Spike's T3 buffer. Also looking forward to trying the EAB and LARB bumper caps on the T3 when I get them. I am thinking I won't notice much felt recoil difference other than a bit softer but better reacquisition as Stuart reported. The full auto rate of fire could be impacted noticeably. I can report on full auto rate of fire but recoil will be subjective. Should be a fun day at the range once I get all the other pieces parts in. Attached File |

I've got a DPM RRS buffer on the way for evaluation and Amphibian has agreed to test it out vs. hydraulic. I would like to see it compared to the LARB buffer as well. I believe mbell? is getting a LARB buffer to test so if he is game I'll send it to him after Amphibian has completed his tests, or mbell can send the LARB to Amphibian, either way is fine with me. The buffer is expensive and there is no test data out there that I could find or videos other than by the OEM, DPM. I suggested that the exposure on AR-15.com and video of testing could help with sales. They readily agreed to send me one. Very fast reply and DPM must have high confidence that their buffer will perform well. Here is the data on weights: With light weight 117 grams (4.13 oz.) With heavy weight 127 grams (4.48 oz) -------------------------------------------- Dear Rick, Thank you very much. Yes I provide a sample for you to test and advertise it in social media. The tracking number is : xxxxxxxxxxxxxxxxx with Hellenic Post office, (USPS in U.S.A.) I send also a spring and adaptor. Attention the adaptor is only for long tubes. For carbine size tubes use only the spring and the buffer. If you use the adaptor in the carbine tube the buffer will be broken. Below is the products I send. https://dpmsystems.com/ar-15-223-recoil-buffer-assembly https://dpmsystems.com/ar-15-set-universal-adaptor-spring Please let me know once you receive it.

The OEM in Greece replied in less than 24 hours. Also posting this info in the other thread I started more on topic for the subject. Test results should probably go here: DPM RRS vs. Hydraulic vs. ? |

Just got back from the range. Test gun was a M&P 15X upper from early 2000s with 1:9 chrome lined m-4 cut barrel, A2 flash hider, and carbine gas system with 2 MOA Sig Romeo 7 put on an Aero/M&P lower (original lower was SBR'd for my work gun). As expected the carbine buffer with no changes to it had the most dot movement and perceived recoil both from bench resting on mag and standing. All three buffers performed about the exact same from the mag rest on a bench so much so I could tell no difference. I'm a LEO so mag rest shooting and standing are the most likely positions I'll shoot from in my city anyway. The LARB equipped buffer when standing felt to be a sharper straight push back into my body but dot movement was maybe by eye 25% less roughly (wild guess) in all than standard carbine. The EAB was the same on dot movement reduction of by eye 25% but the push while also more straight back like the LARB it felt softer but not drastically so, just enough I could tell. Between the LARB and EAB I would have to go EAB for the softer feel and easier install considering the issue I had with my LARB but YMMV. I'll have to try both on my A5 buffer guns I use for duty but not till I can fix the LARB's roll pin hole. For me in my job that lesser dot movement is worth it. Of Note I shot much better groupings with the LARB and EAB when keeping up the same rate of fire so it seems they made it easier for me to properly line up my shots in an event where I have to fire faster than a static range. EDIT: I was able to fix the damage carbine buffer, though the hole is oblong now on one side to fit the LARB a larger pin worked to put the old bumper back on. Still working on making a fixture out of wood to fix the LARB hole alignment. That will have to wait as my lunch break is ending and my partner is covering for me. Good to hear both buffer tips were able to make a difference in terms of dot movement. That does validate that hypothesis that an improved buffer tip will help with AR performance. And at $14, thats about as cheap as it gets for AR upgrades. I had suspected the EAB would be more effective, just looking at its shape / reports that it was softer material. |

| Digital triggers have mechanical backup in case of dead battery right? BATF will surely be looking at that innovation very closely. I'll bet a good ET could print a ckt module to allow double, triple, or full auto fire. Makes my spidey sense tingle a bit. I'll bet they regulate the crap out of it. |

When you had mentioned alternate calibers, I was thinking more traditional like .300 blk / 6.5 grendel / .224V, which really are just the same basic weapon but with a new barrel / bolt /mag. |

I posted a thread about this and have a couple questions. If you can answer them please chime in.
Digital Trigger questions. Questions in that thread are: Is that considered a Class 3 item by itself? Can the Digitrigger work with my RDIAS and would my MG stamp cover it? How can it overcome mechanical limitations of buffer/spring/bcg for a selected RoF? |

Quoted:
Tried out my LARB in my 12.5 Hodge with a Vox K suppressor, H2 and white springco spring. Didn't really feel any difference. Might get another H2 buffer with a standard tip and try both one after the other. Thats a shame you didn't notice a difference with the LARB. I would say a comparison vs the regular H2 would be ideal as a basis of comparison just to confirm. |

Quoted: My line of work molded me into this. If something works there is always always a way to make it better. Bravo to what you are trying! |

I only had 10 rounds to fire yesterday. Mk262 equivalent. Core15 16" carbine barrel, A2 hider, semi auto carrier, standard spring and buffer + LARB cap. Elbow-supported from the bench.
I didn't feel any thump in the back of the tube, but it wasn't like a short stroke. I could sense the full travel. The BCG return seemed a little snappier. The first two rounds were single loaded - locked back on empty both times. Then I did mags of 2+6 - locked back on empty both times. Like I expected it's not a stark difference, but it felt better. Tactilely, <5% effect. |

By comparison, the $100 Kynshot hydraulic buffer is advertised as reducing recoil by 20-30%, lets say 25%. Thats $4 per 1% of reduction. So at $2.8 per 1% of improvement with the LARB tip, thats a bargain If you do get a chance, could you please try a bit of rapid fire? I suspect the dampener will show more effect while trying to track the sights during a 3-4 shot sequence. The Kynshot hydraulic buffer also mentions in their add copy that the most significant effects are noticed during rapid fire: "The RB5000 KynSHOT Marksman Recoil Buffer AR15 Carbine reduces felt recoil by 20-30%, while largely eliminating muzzle rise. To be clear: in this caliber, absolute recoil reduction is small. However, the improvement in weapon accuracy – specifically second and third shot accuracy – is large as shooters report that their time to reacquire a target decreases, and in many cases never leaves their scope sights." https://www.kyntec.com/product/rb5000-kynshot-marksman-recoil-buffer-ar15-carbine-1/ |

Maybe measuring split times with and without the LARB tip would be a good idea? I wonder if taping a small digital postage scale flat to the bottom of the buttpad and then shouldering it (or putting it in a rest against a heavy object) to take a shot, would give a reliable pounds of force reading on recoil? Anyone care to try that? Still waiting on the bumper parts. Anyone beats me to the punch post results plz. |

I plan on using a shot timer/10 rounds in the mag/full auto test for the LARB, EAB, and the 1" silicone hemisphere shock absorber screwed onto the end of the Tubbs flat wire spring if they all cycle correctly.

Quoted: We invested in digital force gages for this very test. It didn’t work. You need a force gage and censor that can record a very quick event. That’s why ended up using accelerometers. All these tests and questions have been answered before, both here on arfcom and elsewhere online. Theses threads pop up all the time.

I just now went to buy the EAB to try out and report back, however it seems they are one of those companies who either like to make a couple extra bucks off the customer by over charging on shipping or they just grab a bunch of flat rate boxes and just toss the item in the box regardless of weight and how much it should cost to ship. Maybe I’m just getting old and bitter but I’m not paying $8 for shipping on something that should cost half that to ship. I sent the gentleman an email regarding this. I’ll see what he says. ETA: Well, his response is they use flat rate $8 envelopes for smaller items. So basically they are too lazy to buy the smaller padded envelopes that are like a couple of dollars and pay the $1 or $2 that it would actually charge to ship. Looks like I’ll buy the LARB. |

LOL. Shot some hefty 45-70 loads last weekend after shooting 2 rounds of trap. Recoil from a .223? https://i.imgur.com/Ro6vYZh.gif It's not necessarily recoil reduction - weight, brakes, and minimal gas + lighter reciprocating mass do that - it's smoothing the peak impulses. Stance and technique does a lot, tech does the rest. More time in the center is better than time getting to center, ja? |

Try it, I’d love to see some numbers MantisX looks interesting but their hardware addon is mostly for handgun and is geared toward training for trigger pull and shot placement. It records motion more than force. They said they are working on a rifle sensor that will also measure rearward forces from recoil but it is a ways off. I sent an email to this guy to see if his system is ready for prime time. If it is and he will send one to me to forward to Amphibian we can get some hard data. His system measures in microseconds. Cheap rifle accelerometer Yeah I know, too much time on my hands....  Retired but not tired.
UPDATE: I downloaded an app called Physics Toolbox to my phone and tried it out by holding it horizontally and hitting the end of it. I'm very surprised with the result. It records in milliseconds. Here is a screen shot of the first part of the .csv (text) file. I can use the data to make a graph with Excel. I think I can mount the phone to my handguard and may get usable data after all with this free app. COOL! The geek in me loves this.

Here is a graph of the first test from slapping the top of my phone after deleting all but one impulse. Total range of about .15 seconds. Blue line represents the 3 second point in the data. Some phones sample data faster than others. Some Galaxy s7, s8 devices can achieve 400 Hz, most phones support between 100 - 400. Any of you guys can download the app and mount your phone to your handguard to try it out. App will email data to you in .csv format to open with Excel or OpenOffice Calc (free) to make a chart with. Chart shows 7 g's total most of the force along the y axis which was with my phone sideways left side up.

I’ve been doing this for years. Getting the actual recoil force generated at the stock is a whole other game. That’s what I was talking about... Glad to hear we have someone in on the discussion with years experience on this, I've only got a few hours so far.
What kind of accelerometer or measuring tools do you use? |

Do you mean pounds of force applied to the shoulder vs. g forces? How about the time period ie. ramp up and down? Glad to hear we have someone in on the discussion with years experience on this, I've only got a few hours so far.

Quoted: Apple phone and Apple Watch, that’s it for accelerometers. Make my own picatinny mounts for them. Even after buying “nice” digital force gages and making fixtures, I’m still not able to capture the recoil force generated in pounds at the end of the buffer tube. And I want it. I’ve got shot tons of data elsewhere.... |

We've seen up to a 20% reduction in ROF/bolt velocities with this cap alone. Up to 30% when used with our LARB buffer. It’s a very simple design modification to the LAB tail cap. Most designs that work well, are simple. Don’t over complicate or over engineer something just for the hell of it. This is a simple design, yet is is engineered, tested and evaluated. It works well, mbell has one of these as well... https://i.ibb.co/Lk9MDJz/633029-C1-032-F-4290-9-E13-8-B69983-E8232.jpg https://i.ibb.co/QpnjNCk/4-BC2414-B-21-D8-4-E33-91-FC-3-F8-DFE7-F4228.jpg photo album upload" target="_blank">https://i.ibb.co/Lk9MDJz/633029-C1-032-F-4290-9-E13-8-B69983-E8232.jpg https://i.ibb.co/QpnjNCk/4-BC2414-B-21-D8-4-E33-91-FC-3-F8-DFE7-F4228.jpg photo album upload Quoted:

Quoted: I may be interested. Weve has tests done many times over the last 3 years, the LARB has always performed well. But, the people testing them? Some not so much. Everyone promises to post results, some do, most don’t. In this industry, I’ve learned everyone is an expert and has a “huge following”. But most just want free stuff. What would be the terms/details? |

What would be the terms/details? Guaranteed the results will be posted and will be well quantified. I personally guarantee you get your buffer back or I will pay for it. re. the Armament LARB Rate Reducing Tailcap: Note that as others have experienced the retaining pin hole in the LARB tailcap is not straight through on the one I received either. Like 99HMC4 said a new hole can be drilled 90 degrees off. I suppose you could drill the hole straight and work in some silicone to fill the gap. Check your jig it may be off a bit or the part is moving. Attached File |
| Well shit. I’m gonna assume the fixture wasn’t set up correctly or even a dull drill could be pushing. I can’t control 100% in production, but if there’s 3 guys so far, it’s the part. The last run of this batch was 75 units. Ill look into it, I apologize if it causes a PIA install. I don’t noticed when I build buffers as we use a press to push and stake the roll pins. I wouldn’t mind sending a buffer, but the best I’d offer is a demo price. These buffers have been out for a few years and have proven themselves (many times here in arfcom too) to work very well. I just don’t give them away anymore... |

havent read all the pages in here yet, but i bought a coupole after they dropped price on shipping... it was even higher before... i have it on a heavy carbine ks-47 and a rifle length mil surp colt buffer. have tried the ks-47 and it was a marked difference. surprising even... that was going from how it felt in the past.... but still, was neat...
for all you commandos out there, buffers are cheap enough that you can keep a spare in a flashlight mount or stock or something no?
