[ARCHIVED THREAD] - Dsa FAL carbine won't run with suppressor

Posted: 10/4/2015 6:16:33 PM EDT

Talk about frustrating. My dsa FAL carbine will not cycle with a can on, no matter the gas setting. I started it off and went all the way to fully open and everything in between. It tries to cycle but fails to completely extract the round resulting in a stovepipe.

Dsa told me the rifle is meant to run a can.

What the hell do I do??

**EDIT---
I'm using ZQI 147gr 7.62, aac 762sd, new mags, and the gas valve is open. No sand cuts in bolt. Also, the gun will run perfectly with no can.

There is a thread here somewhere where they ran a suppressor.

That makes absolutely no sense to me. It seems like a suppressor should make it cycle more reliably not less.

You would think so right?

A little bit more info: the rifle would eject the last round in the magazine fine. It would NOT eject if there were still rounds left.

I contacted DSA, hopefully I will hear back from them today and get some answers.

Update: DSA told me the FAL isn't meant to run with a suppressor. Basically said sorry, though noogies. Awesome.

For the FAL to run reliably with a suppressor you have to modify the gas plug. Go to falfiles.com/forum and join there. There are people there that will modify your gas plug for a reasonable cost. Best to buy another plug and have it modified and save your original. I do not have a suppressor for my FAL but I believe it is an over gas problem.

LG45 gave you the right information. Also, for your reading pleasure:

I am the guy that mods the plugs from FALfiles.

BUT, I have some questions about this situation.

Does the rifle function WITHOUT the suppressor installed?
If so, at what gas setting?

If adding the can makes it not properly cycle, there may be other issues to deal with before the plug.

As noted above, cans generally make the extraction MORE forceful, so unless this is somehow causing some kind of WAY overgassed scenario, I am not sure the plug mods will help.

You can make them work but like everyone is saying you need a different gas plug. I have a full auto DSA OSW that runs just fine with a can. Swap out the gas plug and it should run just fine.

Yes, it runs fine with no can. I use setting "5" with ZQI 7.62 ammo. Haven't tried any other ammo yet. Had 0 issues on settings 4-6 with ZQI.

Stimpsonjcat was kind enough to mod a spare plug for me awhile back, and it has proved to be the answer for running a suppressor on my old DS prefix DSA short gas FAL. While not quite as quiet as my SIG 716, it's more fun.
Thank You, Stimpsonjcat!

My buddy had a sweet DSA Para that kept breaking guide rods. DSA even sent him some titanium ones that he broke. Buddy finally gave up on it, removed the para and sold the gun. Too bad as it was a sweet looking gun.

After more research and thought I decided to keep it suppressor free. In addition to the horrible has in my face the couple of rounds it did cycle, from what I understand the FALs tend to shoot themselves apart when suppressed (per Gunplumber at Arizona Response). I switched bake to the A2 brake and will continue to enjoy the gun as it is. I shoot my Tavor suppressed exclusivly and hope to aquire a G2 recon 308 next year to satisfy my quiet 308 needs
