AR10 in 308 win suppresed.......

[Anon]

More refined, more accurate, cheaper, more customizable, more caliber choices, and buildable by everyone from joe in his garage to top of the line custom shops. Not gonna bash the kel tec, it's unique and choices are a good thing. It leaves a lot to be desired though.

Yes but a .308 ar-10 (what the original topic was about), with a 16” barrel will be about 7” longer. That’s heavy and long with a suppressor hanging off the end. With an ejection port just waiting to blowback at you, giving a nice toxic gas bukakke. For a hunting rig where you would like a short set up, keeping velocity, able to use a restrictive suppressor with no blowback or port pop, and not just a flow thru oss...makes a lot of sense to me.

Have you ever shot a Bullpup? There is a reason they are not any more popular than they are.

Good info. I’ve got one coming together, thinking about slapping on a superlative arms block right out the gate.

The 60 year old gun is more refined and cheaper than a less than 10 year old gun? I believe you

Yes. A Kel-Tec is just a hi point wearing a sport coat.

I'm struggling with an AR-10 in 6.5 gas issue, not-suppressed, i did find out though that the AR-10 uses a shorter buff than the AR-15. This might be a dumb dumb thing on my point, but sharing with the village. I'm going to try it at the range this weekend, next course of action is to replace the gas block w/ an adjustable.

I know a guy …w/a 16” Armalite .308 with Nomad, had to use adjustable gas block turned almost all the way down/ off. Works great now.

Waay over gassed before then.

I just swapped from a collapsible stock to a fixed A2 on my DB10 in 308 so I researched all this.

With a rifle length buffer tube the Ar15 buffer is slightly longer than AR10 and won't allow the BCG to go back far enough. Comparing my new 308 rifle buffer to an Ar15 rifle buffer it's slightly shorter and heavier.

When you go to a carbine collapsible stock buffer tube things get a little more complex. The DPMS/LR 308 pattern rifles that make up most of what's on the "AR 10" market use a standard AR15 carbine buffer tube and a short heavy 308 buffer. Where things get confusing is if you have an Armalite pattern (real AR10) carbine buffer tube. Those are slightly longer than an AR15 carbine tube and use a different buffer than the DPMS carbine.

In short, there a few combos of tube, buffer, spring for 308 ARs and you have to get the right one based on your stock configuration and rifle pattern.

I didn't realize this until I went to Primary Arms to get a new punch set and roll pin for the Gas block so I could remove it and inspect. It is when I told the guy my issues, he looked at my BOM (DPMS/M5 AERO/CARBINE) that he identified the buffer. He recommended the expo .308 carbine 3.8 oz., which is 2.5" and designed for the carbine buffer tubes. Hopefully this is right or i'm bringing it to a smith! Anyone know a good gas smith around Houston

like to hear from anyone out there what can your running (successfully) on a 308 win? THE ONLY can ive found that works is the OSS helix and when i say successfully i mean more than one mag without having to clean the chamber, having a failure to go into battery, or failure to eject!! AR10 platform that is

Rugged Surge 762

I also use Black Diamond lube on the BCG.

had a AGB on it since day one id love to drop it off a your house trophy8! you would be wanting to wrap it around a tree after a couple pig hunts! and yes the DD wouldnt run any Kbaffle can reliably either! AGB foing into a gas tube sending a bolt back im not sure were all the "tuning" is being done

A well built and properly tuned rifle will run.

Take it to a professional if you can’t figure it out. I’m not trying to be an ***. I’m just saying that the platform will absolutely run suppressed and not suppressed when sone correctly. Could be a faulty part on it somewhere too.

Right on thanks for all the info just gonna live with a couple extra decibels,, its runnin like a sowing machine for now!

Yep and this is why AR10 pattern rifles are such a PITA.
