Has anyone cut their ejector spring to minimize the violent ejection of their brass. My case necks are getting the $hit beat out them. I use this rifle for punching holes in paper and want to be able to reload my brass without losing accuracy. I will keep an extra spring handy for SHTF. Just wanted to know if anyone has tried cutting a coil or two off with any success.

Lapua Brass fired once http://i281.photobucket.com/albums/kk216/teflondon100/7.jpg I know it has been done by many with AR15's with success. Some other options are to place the pile side of some hook & pile tape (Velcro) on the brass deflector, or the slickside and rear opening of the ejection port if you have an LR308 low-profile receiver, which mitigates the neck dents commonly seen on .308 cases from the AR platform. Another additional option, in conjunction with the pile tape, is to run a quality brass catcher, such as this one: http://www.brownells.com/aspx/search/skudetailv2.aspx?sid=6119&pid=1541&tabid=0 You can place a Tupperware container right underneath the opening of the brass catcher, with the zipper opened, and control your empties that way. |
| Yes it is Armalite AR-10. The Barrel is Noveske. The dings on the neck seem to be coming from the locking lugs and not the brass deflector. Even though I get a ding on the case body from the deflector, I don't worry as much about the body dings. I am concerned about consistent neck tension reloading these cases. These are some deep dings, and I have managed to get them straight with a lot of effort. Not something I want to do all the time. So I wondered if I cut a coil off my spring if it would lessen the blow to the lugs as it was ejecting and still get the case out of the weapon. What I worry is that it wont eject completely and send another round on top of the empty case really destroying my spent case. |

The vampire-like scratches are from the barrel extension, while those larger dents in the necks are more likely from the rear edge of the ejection port. AR10's are pretty hard on brass, which is why I only use Lapua brass to reload for them in .308. I've seen some gunsmiths do a meltdown on all the sharp edges in the AR15 and AR10 barrel extension and feedramps, but others have been leery of taking much surface hardness off those critical stress parts.
I would try the velcro first and see if it gets rid of the neck dents. Then start cutting ejector coils one at a time, but we've never had to resort to that. The body dents have never posed an issue for me or all the guys I know that load for the AR10, as they fill out upon firing, and I have yet to see a case head separation in the AR10...don't ever want to! |
