Does or could anyone reproduce the old style full round carbine buffers found on XM177s
UPDATE live4nov has created a prototype for testing. http://www.ar15.com/forums/t_3_123/693462_Full_round_carbine_buffer_SP1_carbine_and_XM177E2.html&page=5#i7194241 |

I was thinking about it actually. I made some Acetate ones, then I did a few aluminum caps for carbon fiber bow stabilizers the other day for a guy building me a website and they were similar to buffer bodies. I also saw some gold type 2 at my anodizer that looked close to the color, just didn't have the green hue.
I just have so much going on I don't have the time to play with it. Im sure someone here could make them pretty easy though. |

it would be awesome if you could make some. JT might be able machine them too he used to make edgewater bodies.

Awesome let's see it anodized the correct color. I think they were gray. <a href="http://s268.photobucket.com/user/tom051876/media/2016-04/68A0DDFD-EEF3-48D3-8472-D85DE69A2E31.png_zpsfcpigily.jpeg.html" target="_blank">http://i268.photobucket.com/albums/jj19/tom051876/2016-04/68A0DDFD-EEF3-48D3-8472-D85DE69A2E31.png_zpsfcpigily.jpeg</a> View Quote I have an original that is gold with a wine colored buffer |

Retro heads will be canabalizing thier modern buffer weight and rubber pads! Think of all those XM clones with original style buffers. It would be amazing |

I've got a full rounded black one. What'd it go in? The only thing I know is they're harder to get in the tube. Have to press in detent while trying to install.
|
|
lets get some pics up of the different colors and such you guys have. Who is doing anodizing on here and wants to mess with colors? mine is to far of a drive and Im leaving town for a few weeks.
Where should a mark be put to show its a repro? I have some small letters, or I could prick punch it on the bottom side of the face? |

Black full round carbine buffers I think have all been commercial dupes.
Per BoyWonder, HKiller & HipSh0t here: https://www.ar15.com/archive/topic.html?b=3&f=123&t=679369 The old SP1 carbine buffers have been the kind of darker bronzey-grey, with non-translucent yellow/red-wine bumpers. see here: https://www.ar15.com/archive/topic.html?b=3&f=123&t=525487 and here: http://www.gunbroker.com/Auction/ViewItem.aspx?Item=550951416 |

Correct, only the later buffers had the bumpers pinned. Early ones were just inserted. (I don't know if they're just friction, or if there's some kind of lip that they seat into?)

I bought some all round Colt's from Brownells many years ago. Probably around 2002. Were in Brownells white or yellow plastic sealed bag (I may still have packaging) but it said Brownells / mfg Colt and were purchased and charged as such if memory serves. Thinking they were $22ish each at the time. They had modern snot / light lime colored bumper and were pinned and anodizing was gold to green if memory serves. They were sold or traded to a couple members here so should still be around. Think I still have one in a carbine somewhere. Don't usually dig that far into them and just annually cleaned 10 uppers yesterday.
Liv4Nov, I think stamping a R for retro on face like the H buffers before anodizing would be cool. We would all know what it meant and probably get a chuckle out of a far fetched story 10 years from now if you made and circulated a few. Very nice job also. Homebrewed stuff like that makes me a little paranoid but lots of gun related stuff makes me paranoid even from known firearms mfgs. I don't know time frame for carbines but for rifle, pinned buffers were part of the A-2 upgrade according to member who worked on Colt A-2 project and earliest was for USMC 1983 due to bumpers flying apart in extreme cold weather. Other branches were later. I've seen dated packaged pinned rifle buffers earlier but have always been a little suspect on those based on what I was told. Think member was Coldblue or such. I usually grab the wine colored bumper pinned buffers when 100 box shipments come around and they still show up today but very limited. Usually 3-4 out of 100 at most. |

Urethane. I don't know the density though, can't find it in any of the reports.

I'd bet anyone could turn these out for a few dollars each on a CNC.
my guy could as long as I give him specs. Minimum would be 100 parts. |

Don't mean to go OT. But, seriously, if someone is able to make the EW buffer bodies, That would be great. |
|
The bodies would be simple to make. The bumper depends on the hardness of the urethane. May be able to freeze it in liquid nitrogen while its in the chuck and cut it then.
|
|
Waiting for word, but I may have some early bumpers from demil buffers coming from a friend in or near Indiana.
|
|
Bumpers used to be available. Weights would be another expense. Lots of different weight buffers out there today. Numrich had bumpers, haven't looked lately. Thinking Brownells also. Be nice to deal direct with sub contractor for parts. Not unheard of.
|
|
I have plenty of new bumpers and weights, steel, tungsten, etc for making acetate buffers, and my own stuff. The tungsten weights are only like $6 each on KAK. I am hoping to get some old ones though. Are the ones on numrichs old, or new? I have real problems finding anything on their site.

Don't count on any of Numrich's photos to be accurate. But, it's probably sill worth buying a couple of their bumpers to find out.
|

I wonder if they will do a discounted price, I could probably make the bodies pretty easily. And mark them as repro's. with the weights, spacer and bumper alone we are at $18.
depending on who is anodizing (victor will be close to $10 ea.) so $28 with out the buffer body machined. |

I've made weights from old carbide endmills. Cut the shanks of the endmills with a diamond wheel. Couple guys here have white Delton faux early buffers in their 607's, made like so. I added the urethane bumper, assuming that Colt added them for a reason.

Any one have dimensions for a buffer? im at work and dont have one on hand to measure.

Tungsten weights can be cannibalized from existing carbine buffers. Weight should be 2.9 oz. I wanted to be able to tailor the weight for relatively smooth operation of my 607. I believe original 607's had gas ports of about .100-.110. I used a modern gas port size like the mk18's. Sure, I could have cannibalized a couple buffers for parts but didn't want to do that. At the time I did not know that you could buy individual buffer oarts, plus, I'm a cheap bastid. |
