Suppressed gas system

[Rogue111]

Hey guys, I plan to order a 16” varmint upper for my AR that will be exclusively suppressed with my 30 cal can. Do you see any benefit of having a midlength gas system over the shorter alternative? I’ve seen a few opinions stating longer gas systems can smooth out the cycling & reduce some of the blowback? I’ve conducted a search without much success, I apologize if its been covered & I missed it.

Thanks in advance!

Well, I can tell you that mid length is smoother and from my experience, it has a little less blowback, but the best way to eliminate that problem is by putting the RTV silicone on the charging handle.

Never tried the gasbuster ch.

The longer gas system is almost universaly the better option and even more so when running suppressed.

An adjustable gas block would help with recoil impulse, cycling, gas in the face, etc. also.

Short answer=yes, most shooters prefer mid-length gas over carbine. For a dedicated suppressed rifle I would definitely go mid-length on a 16" gun. Another thing to consider is your buffer system. I'd look into the Vltor A5 system with either an H3 or H4 buffer. This video explains the A5:

Also, as others have already stated, I would look into an adjustable gas block such as the Noveske Switchblock. Definitely do your homework before buying a rifle, you will save yourself alot of time and money in the end.

A 16" gun should run with or without a suppressor with carbine, piston, or mid length systems.

SBRs are going to have the problem cycling with/without the can. That's where a switch block is really going to help. The switch block will cut down the blowback, but isn't necessary in a 16". I'm not saying that it's impossible to have problems, but I've been through 3 separate 16"ARs and didn't see an issue. I would put the money towards something else.

My experience would be mid length gas tube.
