Title: Supressor = Dirty AR ; Anthing I can do?
Post by: Rastus on December 30, 2007, 10:06:52 AM

OK, I've got a good problem.  I've got a can for my AR-15.  It's a hoot.  Despite putting a little extra gas in my face (oh well) everything get's really dirty really fast (as I heard, a gun that pukes in it's own mouth).  Is there something I can change out in my weapon since the can put's more gas down the old gas tube?  Heck, I haven't ever had such dirty clips before.

Thanks,
Ken

I have a really good contact for this issue, if he will ever call me back. Bushmaster rep with the same hardware you have. I'll get back ASAP. Mac.

Finally spoke to the Bushmaster rep about the fouling problem with a can. "Yep, they just do that. And it's about four times nastier with select fire models". He said changing ammo won't really help either. The only cure is to go at a push rod system and that design work is being done, but there are problems. Sorry for the lack of good news from here.

Back when I was an active duty Mrine (WAY back) we had the same problem with blanks, 1 or 2 mags worth and you find out why the forward assist is there. No big deal for a toy but if you're using it in the real world it can get you killed.

Rastus, how many rounds does it take before this happens, 10, 50, or more.The suppressor is a special use type of tool. In our normal invironment, how many rounds need to be suppressed. Here in the US, we might think that the more the merrier, but as far as a shooting system, it takes more maintenance. I do not have the owners manual of your particular suppressor. Look it up, and talk to your rep, about cleaning the suppressor and what you can do to prevent the conditions your experiencing,. May be that's as good as it gets, but maybe not.

Clean it after every session! :D

Yeah, unfortunately suppressors really gunk-up an AR fast.  My setup is good for about 500-750 rounds before bad things start happening.  I can extend that a bit with copius amounts of oil, but that just ends up creating a bigger mess.

The piston systems work a bit better, but they are more expensive.

Sort of on the same topic, the Army has conducted a dust test between the XM8, Scar Light, HK416 and M4.  Here is the bottom line of the test:

Officials tested 10 each of the four carbine models, firing a total of 60,000 rounds per model. Here’s how they ranked, according to the total number of times each model stopped firing:

• XM8: 127 stoppages.

• MK16 SCAR Light: 226 stoppages.

• 416: 233 stoppages.

• M4: 882 stoppages

Here is the original article in Army Times (http://www.armytimes.com/news/2007/12/army_carbine_dusttest_071217/)

Piston System for the win!
