I have a Rock River Arms A4 varmint that I shoot primarily from a bench and am looking for a way to reduce the ejection force of the MT cases. I shoot in matches with it and am concerned with the shooters to my right. I simply drape a towel over the gun to contain the brass on the bench however occasionally one will get out and I'm thinking if I could reduce the ejection force that would help matters.
Thanks |

Stronger buffer spring, heavier buffer. All my AR's toss brass at the 4 to 5 o'clock position about 6 feet back, I never come close to any other shooter. That won't change how hard the brass is ejected, just the direction it's ejected. OP, take your ejector out of the bolt, start clipping a bit off the spring until it ejects the way you want. Have a spare spring standing by just in case. |

| get a brass catcher also a small rubber or felt pad on the deflector helps too. I got one of the cheap 10$ veclo UTG brass catchers and stuck a 6 inch hose clamp on the inside to make it stay open and dont zip the bottom of it , brass falls right next to your rifle on the bench. |

Carrier speed changes the direction of the brass. Ejector spring changes how far it goes, i.e. how hard it's ejected. |

Thanks Wolff extra power spring and a H2 or H3 buffer. I use both these set-ups in my RRA mid-length rifle and they work great. If I'm running XM193 I use my H3 and everything thing else I use the H2. The H2 will run most ammo but the hotter loads I use the H3. |

You may have problems with lighter ammo such as commercial/223 or even hand loads. I say this because if you shoot match you are probable not shooting the 5.56 bulk ammo. I had to switch back from the above set up with my RRA and I have a car system. Worked great on the xm193/85 stuff. Your best bet would be the brass catcher. Or just look to the guy next to you being pelted by brass and in a stern voice say "NOW PICK THAT UP" and keep shooting  .

This. Ask in the Highpower forum as many do this. When I clipped mine it put the brass in a nice pile at 2 o'clock. And no, it did not affect reliability. |

Thanks I use Jewel Precisions adjustable gas block on my 20" AR and it works perfectly. Simple set screw in the path of gas flow from barrel to gas tube, just dial it dowl turn by turn until you have it spitting brass in a nice neat pile but dont get too aggressive or it will start to short stroke. You can also run the system closed and the rifle will function like a bolt gun, cycle the action every time with charging handle. |

I would leave it alone ,I'll bet the shooter to your left isn't going to clip his spring for you.Getting sprayed with hot brass is a part of shooting,just make sure everyone has eyepro. This. You can alter where the brass falls with some self stick Velcro |
| I have a different but related issue- my brass seems to be ejecting straight back, like it's trying for just about 6 o'clock. Bangs the hell out of the receiver right at the base of the brass deflector. Not concerned about the aesthetics of having a banged-up deflector (I know that's what it's for). But I am concerned that the ejection pattern indicates some sort of problem with my internals- spring too heavy? Buffer too light? What should I do to get it closer to 4 or 5 o'clock? Other threads I could find weren't too useful... |
