Does anyone actually use this method for a spacer on this site? Or are most just getting heavy and longer buffers with heavy springs? Would just like to know the success people have using the quarter method with a carbine springs and a slightly heavy buffer (about 5oz) but normal length like the one that comes with PSA's 9mm complete lowers. If you go to the 9mm trigger thread I started, many of the buffer/spring combos are listed. Also...using quarters is ghetto, when there are bumpers available that are designed for the application. And...there are quite a few buffer threads from the last 8 months. I would read those for more info. . |

The few dollars that a bumper costs is well spent. Why rig something if you don't have to. Either get the bumper to use with a standard length 9mm buffer or spend the money for an extended length 9mm buffer.

I use a rifle buffer and tube, along with a NFA bumper... a quarter or two makes a cheap shim to fine tune the length of the action... I don't use a last round bolt hold open

I think it is quite a leap to say using quarters as a spacer is ghetto or wrong. They are the right diameter and it is easy to fine tune the amount needed to the specific setup.

I did, and at $1.50/$1.75 (i forget now)worth it worked great, i had no fte or double feeds, i swapped it to ss washers, since the buffer i wanted was still out of stock and gave the kids the quarters for school haha.

Hey, it's a great way to stash a few quarters in case you need to make a phone call or buy a condom.

It means poorly conceived, designed and constructed. The point being....why spend $700 to a grand on a firearm if your just gonna put some loose change in the buffer tube ?? A cheap and easy to install component that is bomb-proof and solves a problem is available, and has been around/discussed for a few years. _ |

While i do not currently run $1.75 in my buffer tubes, I did for a few years.
Worked well, quite a bit cheaper than a poly spacer. Branding something "ghetto" is simply foolish. |

Nothing wrong with quarters...
I started out running quarters and C product mag block, yes it worked great too just didn't like flat nosed bullets I used quarters for couple years many thousands of rounds I've also used spacer and RR 9mm buffers, also worked great What I'm running now, I have two 9mm ARs 7 1/2" pistol and 16" rifle both function perfectly 100% reliable both use Spikes extended 9mm buffers Tubbs flat wire buffer spring's and Colt style dedicated Lowers, DDLES and BCP IMO less parts = more better |

I do not use a buffer detent with any of my PCC rigs. So what I do is drink down the differ tube threads and "adjust" the buffer tube to take up any extra "play" in the bolt/buffer travel.

I use six quarters in all three of mine, along with a 5oz buffer and standard carbine spring....works just fine after thousands of rounds. Running my first one over a year and a half at every match I can....works great!!

I used quarters back when then switched to a bumper. Both worked well!

I started to use quarters to determine functional length but was doing AC work and found that the rubber plug for the drier was the right diameter/length. Saved me from ordering the plug...

I posted it here a while ago as I had not seen it mentioned anywhere. The A5 length buffers are the correct length and are available in a wide range of weight options to allow a quick and easy drop in design from a company that's been around for a really long time. Further they have been tested in exhaustive military standard tests and in combat. Not saying that some of the other options won't hold up but it's nice to know what's been done to verify that you are buying a reliable product.

On could take quarters as spacers to a whole new OCD level like I did for my QC10. Sorted a pile of 50-state quarters by their 2A stance... Only those worthy made it into the buffer tube. Figure in a hundred years, someone will take it apart, discover the quarters and connect the dots. Kind of like finding something in the buttstock of a CMP Garand.

I admit that $1.75 of the approx. $1050 I have into an AR9 consists of seven quarters in the back of the buffer tube.

I don't use them or "extra power" springs.....a properly weighted extended length buffer is all I have ever needed with a carbine spring to make my guns run smooth and reliably.

Yes, a buddy who knew what he was doing helped me tune my PCC using quarters. It did help with the bolt cycling speed and how much sight movement I saw during recoil.

what buffer were you using and how many quarters did it take? I would defer to someone like Max, who helped me put this PCC together. You can see him posting under Maxamundo on the Enos forum: http://forums.brianenos.com/topic/250677-which-recoil-system-jp-scs-gen-2-vs-mbx-pcc-buffer-system/ |

After further consideration prompted by this thread, I have taken the seven quarter stack out of the AR9 buffer tube. With the quarters at the back of the buffer tube, the bolt travel is limited, but the recoil spring is given a greater than standard pre-tension. Further, impact of the bolt, even with its buffer, tends to cause some rebound off the quarters. I have put in a plastic spacer that fits snugly inside the recoil spring at the back of the spring. The spacer is approximately the same length as the height of the stack of quarters, and should cause less bolt rebound.
I have not yet fired the carbine, but the rear impact of the bolt feels more damped when manipulated by hand. And, as expected, since the length of the bolt travel is limited the same amount as before, the LRBHO works. MHO, YMMV, etc. |

Have since moved on to a Heavy Buffer and still have no issues. |
