| Hi guys just need some input. I have an Rainier 18" Match 223 wylde that I took out today. I ran into ejection at 1-2 o'clock, and dinging the deflector pretty good. Now the thing is it is a full rifle length with Luth-AR stock. So 1 to 2 oclock would most likely mean over gassing. What options do I have that don't involve me taking the gas block to a new one. I would appreciate any help. Thank you guys! |
| So no it is not an adjustable gas block currently. I only fired about 15 rounds through it today to sight in a new scope. Literally though the AR was ejecting and feeding fine, but there are some pretty good marks on the brass deflector, not just a smear but I can make out crescents. After hitting the shell deflector it ejects between 1 and 2 oclock which typically means "over gassing" Is there a way to adjust this via heavier recoil spring? With it being a rifle stock and rifle gas system? Sorry for any confusion. |

As long as it's cycling fine, I wouldn't worry about it. There are many things that effect ejection pattern like gas pressure, buffer resistance, extractor tension, ejector tension, ammunition, etc. You could try running a heavier action spring (buffer spring) like one from Wolff Gunsprings, the heavier spring will slow the action going rearward, and it will speed it up going forward. You may also consider using some different ammunition to see what results you get.

I will try some m855 next time to see what it looks like. |

Does it feed?
Does it eject? Do the ejected cases look ok? No problem then. People look too much into that stupid ejection pattern diagram. A lot of other things can affect ejection patterns. As long as everthing works and the rim isn't being torn off the case, nothing is wrong. |
| What is the reason you don't want to change the gas block? If you go through all the tests and really determine it is over gassed, a good adjustable gas block can go a long ways to fine tuning your rifle. I run them on pretty much all of mine, but I like to be able to tune each rifle depending on conditions, ammo, and so on. |

As long as everthing works and the rim isn't being torn off the case, nothing is wrong. All of these things can impact bolt carrier velocity and ejection pattern. I wouldn't worry about it. I have shot enough rifles that I can generally feel when a rifle is overgassed. Generally when you add suppressors to barrels designed to run 223 ammo without a suppressor.... is when you get into territory where you need to adjust your gas. If you feel the need I would start with a heavier buffer or a heavier action spring as suggested above. Unless you can really feel the buffer slamming home in the back of the receiver extension as you are firing the rifle, I wouldn't go adjustable gas with an otherwise factory setup. |
