mineralman55 Posted February 17, 2016 Report Posted February 17, 2016 How often do you AR15 shooters need to change out the gas rings? I've had to change mine out twice now, each time after probably 1000-1500 rounds. I shoot 77 and 69 grainers, and I don't load hot. Clean and lube the rifle after each session so it's not neglect. Is this normal?
blue109 Posted February 17, 2016 Report Posted February 17, 2016 I've only replaced one set, and they burnt bad. Not sure what happened but it wasn't wear and tear. I have a family member with an early 80s colt that far as I know is still on its original rings with many thousands of rounds.
392heminut Posted February 17, 2016 Report Posted February 17, 2016 I've never had to replace gas rings on any of mine yet.
sketch Posted February 18, 2016 Report Posted February 18, 2016 Shooting buddy had to replace his in a daniels after 3k rnds all mine have been going strong for over 5-6k rnds but being such a cheep small part i should pick up some spares just incase? I had to replace my trigger in my pre ban oly but rings are solid. Bought used 20 years ago from a guy that was cutting trees in half with a diferent trigger ? ( rnd count??)
survivalshop Posted February 18, 2016 Report Posted February 18, 2016 (edited) I have the same everything in my Oly. pre ban, but the upper receiver , I put a TM on it for a scope , but no problems with the Gas rings & I built the rifle around 1979-80. I think the test is , when clean , push the Bolt into the Bot Carrier & flip it to post down & if it stays the Gas Rings are good . I can't think of any AR I have owned has ever needed new Gas Rings , thats including Select Fire M16's .? Edited February 18, 2016 by survivalshop
Malig8r Posted February 18, 2016 Report Posted February 18, 2016 I believe that according to the TM, you are to fully extend the bolt and then place the BCG with the bolt face on a flat surface. If the bolt remains extended the rings are good. If the bolt slides back into the BCG when placed on the flat surface, it is now time to replace the rings.

Had an M-16 in the service that needed rings, who knows how many rounds that Vietnam era rifle had fired though.
Frankh252 Posted April 23, 2016 Report Posted April 23, 2016 I bought a Ballistics Advantage BCG to compliment one of their 18" SS barrels but they don't offer replacement parts for their BCG's. I wonder if a spare set for another brand BCG would work just as well, if they day were to ever come that the originals needed to be replaced? I hope I never have to shoot it that much/can't afford all the ammo haha

Should use std Gas rings or the Mcfarlin type , be it a 5.56 or 308 .
blue109 Posted April 23, 2016 Report Posted April 23, 2016 If I remember right, the "ring check" according to the TM was just to remove the cam pin and hold the carrier with the bolt facing down. If it falls out, you might need rings. I've seen old beaters that failed that test and still ran fine though. The rings I replaced looked like they were hit with a welder. Blue and melted around the gap. The gun still ran though

Or, Ballistic Advantage BCG's are just so good they don't need to offer replacement parts...yeah, I'll go with that haha
washguy Posted April 24, 2016 Report Posted April 24, 2016 The only time ive replaced rings was on a brand new 308 bcg where some nitwit jammed the bolt in the carrier and pinched a ring ...they had to know they did it too...cause the bolt was stuck Wash
JF89 Posted November 13, 2018 Report Posted November 13, 2018 (edited) Just changed the gas rings on my Colt 6920, I have 7k rounds through it. Edited November 13, 2018 by JF89

Is this normal? Does the appearance of the rings (being burnt or discolored) indicate when to change the gas rings or do you use the TM test to decide if the rings should be replaced ? I figure that if the sealing edges remain shiny, making contact 360 degrees, they should be good to go
ARTrooper Posted November 14, 2018 Report Posted November 14, 2018 visual should always be a sign of wear. if you are a climber, just because you do a test pull on your rope and that pull shows it has plenty of strength to hold you, doesn't mean you should climb with the rope if it is starting to visually fray.
mrmackc Posted November 14, 2018 Report Posted November 14, 2018 Trooper, I see and understand your reasoning there but don't quite connect with falling screaming to certain death whilst also shatting your BVDs, (fuckkedd up rope)to a simple f2f, or f2 chamber a measley.223 round (messed up gas rings,that aren't absolutely a critical part of a midget rifle). LOL BTW, don't take this old fart too seriously.... After all my go to rifle in a SHTF situation is a .3006 home built custom Springfield 1903A3 with a Weaver K4 scope sight!

Sounds very familiar, Mack. Here's mine - 1903A4 with a Weaver K4. Are you POSITIVE that I'm not your illegitimate son?... Edited November 15, 2018 by 98Z5V
mrmackc Posted November 15, 2018 Report Posted November 15, 2018 Well maybe I have had a few anxious moments kinda like out of mind and body experiences while wearing the green side out garb

I was just trying to do a comparison that shows wear can lead to failure... guess I shouldn't have used on that would lead to death. haha. Ok, try again... if the tread on your tires is getting low and showing wear, you might be able to drive hundreds or even thousands of miles on it. but there is also the chance you could get a flat tire easier. Better comparison? lol.

ARTrooper Posted November 16, 2018 Report Posted November 16, 2018 I'm pretty sure myself and those I work with are the crazies. haha
Slevin182 Posted March 18, 2019 Report Posted March 18, 2019 Every few thousand rounds seems fairly frequent, but it certainly won't hurt. Some manufacturer's have different specs. I built an AR-308 rifle w/ all JP internals that I ended up selling before I even fired it, but there was a blurb in some of the paperwork that came with it saying it wouldn't pass the standard gas ring check, and then went on to explain why. Can't remember exactly the reason.
jtallen83 Posted March 19, 2019 Report Posted March 19, 2019 One would be to slow it down a bit, it would be like a set gas bleed off valve. Most generally 308 AR's can use a little taming.
