    Got a question guys. I haven't shot my rifle for a while and got it out today to get ready to shoot with a friend this weekend. Anyway, when I pulled back the charging handle I heard a strange noise, also the bolt wouldn't stay locked? Opened her up and found that the buffer was pretty much totaled.
    18" noveske, non adjustable gas block
    M42000 can, mostly shooting 55gr lake city green tips.

    If you're running a can without adj gas or some other means of taming the gas, then yes, over gassed!

    I should have adjustable gas block on all suppressed uppers then? I honestly thought that was a preference thing, thanks.

    I've never seen a buffer bulge like that, and I run my rifles suppressed all the time (all the ones with the adjustable gas, actually don't ever get adjusted). Was it a factory built rifle? Home build? If it's a factory rifle, I would call noveske and they will make it right, if it's a home build, I would swap to a heavier buffer to slow things down, and go with an adjustable gas system.

    I would also advise to check the buffer tube to be clear of debris, also what brand and weight buffer , spring ?

    That's not entirely true.

    You'd be surprised how many guns are out of spec and run fine unsuppressed, but are catastrophic suppressed. In spec guns should be okay suppressed.

    As a left handed shooter I noticed a huge difference in gas in my face after in installed the Govnah, it's a pleasure to shoot now, I also have a 10.5" Noveske ( I would think it'd be in spec, but who knows?) that I almost hated to shoot, I put a suppressed BCG in it and no it to is a pleasure to shoot. Even if the gun is in spec the can does increase back pressure, so regulating the gas some how should/would be a good thing

    Not a factory upper, never had an issue before. I ran the upper for a while on my sbr lower when I was waiting for the stamp, compared the 2 buffers and the other one looks just fine. The one that mushroomed, don't remember where it came from. The other lower never made a sound while shooting, but this one did as soon as I started running with the can. I would always check my brass and it was always good, a little dirty but no ftf, or jams or damage to the spent casings.
    After looking around tonight, I'm leaning towards bad cheap parts, China. I'll change out the buffer and spring 1st, we'll see what happens then. Thanks for the info!!

    On this tool I'm running a magpul ubr, same setup as my 300blk sbr. The buffer that is damaged doesn't have the roll pin and seems to be pretty cheaply made, I'll start with that first. Thanks again

    Brandonlsu, my mistake on the weight, thanks for pointing it out, that might have been the problem all along.

    I agree with all of that, but I should have clarified my point that something is going on with his rifle and an adjustable gas block is a band-aid on the wound. He needs to figure out why it's so overgassed it is destroying buffers lol. I've honestly never seen that before.

    Sounds like your buffer is made of pot metal lol. I'd do like you said and swap it out for another buffer and a good spring.

    What was the markings on the buffer? H,H1,H2 or no markings at all?

    No markings at all, no roll pin either. My other one isn't marked either, but it has a roll pin. I don't remember where I got it, it's been a while and 21 and 7 doesn't give me a chance to shoot like I was able to before.

    Blue spring from spingco?

    Sent from my SAMSUNG-SM-G900A using Tapatalk

    That's what I would go with, but I'd also order the red spring, and test both.

    For reference:

    "WHITE Spring" STANDARD Power Buffer Spring. Equivalent spring load to a *fresh* Mil-Spec M4 Carbine Spring. This spring will perform reliably in any properly configured and maintained 5.56 Carbine, if you wish to maintain the performance of a *fresh* Mil-Spec load spring without concern for replacement. This is the best choice for shooters and purists that wish to maintain the performance of most factory supplied NEW Mil-Spec springs, but do not wish to be concerned with frequent replacement of same or do not have the time or inclination to seek enhanced performance options. The "WHITE" spring is recommended for 10.0"-11.0" SBR's with H2 Buffers, 1st Gen M&P's, older RRA's with under 18"+ BBL's, early generation Colt 6920 LE's, 5.56 & 6.8 SPC 7.5"-8.5" BBL Piston Guns with H2 Buffers, with few exceptions, most .300 AAC Platforms, longer carbine barrels using intermediate or rifle length gas, and when training with SRTA and other low power and light charged *budget* rounds. Color Coded WHITE. [EXCEPTIONS: With SBR's which are seriously overgassed firing suppressed, (e.g. 10.3" HK 416's), a RED or ORANGE along with a hydraulic buffer is often used with great success.]

    *BLUE Spring* ENHANCED Power Buffer Spring, Offers improved performance with most non-suppressed 12.5"-14.5" SBR's, 16" DI Mid-Length BBLS, and all mid-length uppers with adjustable gas blocks. Best performance is usually achieved using buffers ranging from ST-2T, H2, DPMS Extra Heavy Buffer. Will run in 18"+ Length BBL RRA'S with ST-T2 Buffers. Color Coded BLUE.

    *RED Spring* EXTRA Power Buffer Spring, Best option for 16"+ 5.56 barrels with carbine length gas system platforms with standard front sight towers and H buffers, 16" + BBL gas piston guns, *some* suppressed shorties,and later generation Colt LE6920's, 9mm, 6.8 SPC, 6.5 Grendel, .458 SOCOM, 450 Bushmaster, .500 Beowulf, and assorted "Thumpers" using standard 7" depth M4 extension tubes. AR-10 Carbines (E.G. Armalite, Noveske, LMT) using deeper extension tubes and standard length carbine buffers to accommodate the longer .308 BCG also use the "RED" Spring. Please call us to discuss successful historical "recipes" for implementation of the RED spring in .308, 6.8 SPC, etc. RIFLE length extension tube platforms. Color Coded RED. NOTE: NOT for use in .308 Carbines using standard 7" M4 extension tubes and short, stubby buffers. (Use our "ORANGE Spring" below for that specific platform approach application.) NOTE: If you have a seriously overgassed .308 Carbine which has the deeper AR-10 platform receiver extension tube running an H3 buffer firing 175 Gr. Projectiles and / or suppressed, many shooters have experienced success using the "ORANGE" spring, as it is still heavier than a "RED" spring in that application.

    "ORANGE Spring" The ONLY specifically engineered EXTRA POWER Buffer Spring for .308 Carbine Platforms using standard 7" Depth M4 extension tubes and .308 short 2.5" buffers (Including aftermarket "heavy buffers.") You cannot clip coils from any other commercially available buffer spring to yield the proper spring loads for this application, especially in heavily gassed .308 carbine platforms. We started from scratch on this design to provide Operators with a viable alternative to existing OEM and aftermarket offerings. Platforms known to exist using this approach include DPMS, Bushmaster (Post 2010), Remington, CMMG, Mega, SA Defense, Colt 901, Rock River Arms and many others. Color Coded ORANGE.

    "GREEN Spring" In addition to use in 5.56 Fixed Stock Rifles, our *GREEN Spring* is just the ticket for use in the VLTOR A-5 Stock System using their appropriate weight buffer for maximum versatility in tuning almost any upper configuration, running both with or without a "can". Color Coded GREEN.
