Hi guys,
I recently bought a new PSA 18" CHF 223 Wylde 1:8 Rifle Gas SSK 15" running on a PSA lower with Magpul CTR, Carbine length buffer tube, damage industries chrome silicon spring with Spike ST-T2 buffer. Since I'm running the rifle length gas system on a carbine buffer I wanted to know if the brass casings are ejecting normal. Can someone tell by looking at the brass deflector marks? Should I get the H2 buffer? • Here is the PSA 18" CHF 223 Wylde: PHOTO to compare • Here is my PSA 16" Carbine: PHOTO Btw. I used CLP, frog lube, Hoppe’s Elite cleaner, rag, and eraser but nothing's removing that brass mark. Anyone know what else I could do to remove that? Thank you! |
| Hoppes #9 usually gets the brass off for me but I usually don't worry much about it. An H2 buffer is only going to to be about .4-.6 ounces heavier over your ST-T2, which won't make much difference IMO. You could always buy some tungsten powder at your local golf shop and play with the weight. And there is also the Vltor A5 system. Personally, I'd leave it alone or use a H2 only to get rid of the ST-T2. Your brass deflector is doing its job. |

Here's a slow motion vid that shows ejection rather well
AR ejection,.....sloooooooooow mo |

I'd probably increase the weight of the buffer. Mainly because I don't care much for collecting brass from ahead of the firing line, or having it bounce back at me shooting around barriers. When my carbine had an H buffer in it, it tore my brass up trying to extract it while the chamber pressure was too high, bad for brass, not good for the bolt either. Posted Via AR15.Com Mobile |

Quoted: Sorry to hijack slightly but my deflector still looks new, nothing done to it. But none of my brass hits it. Not going to change anything but is it over gassed? DD 16 mid A5 RE M16 bcg. Approx. 1,000 rounds. When the ejector ans extractor springs are new the tend to be more aggressive in the extration which causes it to hit the deflector....as they began to weaken the ejectection moves forward. Chances are your set up was spot on. |

Cover it up with some tape and run her for some more rounds...it should move forward and away from the deflector as the springs begin to soften. Your better off having a strong ejection at the beginning than a weak one... Thank you. My PSA NiB BCG came with really tight extractor. I have a heck of a time inserting the roll pin. Maybe that's the problem. |

When brass deflects off the deflector it leaves a smear mark, as if it was painted, and lands somewhere between 4 -5 o'clock.
Your brass deflector appears to be cut to bare aluminum through the anodizing, most likely by the case mouth. You can correct it by installing heavier buffer, weaker extractor spring, and dumping the rubber o-ring if it's installed. |
