Not really. If it works in one it will work in the other. Lots of guys running 14.5 and 16" guns at very high speed. When the targets are almost always 4MOA or more, 3Gun is not really precision. Most mid-level to novice shooters in 3Gun suffer with rifle because they shoot too slow or don't understand mechanical offset. 16" probably is optimal for most 3Gun matches.
Yes, the POI will shift a bit more with a pencil and the groups might even open up a tad. However, we are not talking about more than an inch or so at 100. I shot a 16" Pencil barreled AR at all 3 of the CTC midnight matches, one time suppressed. For all practical purposes there was no shift that made any difference out to 200 yards. I would choose the barrel I want to use the most and then deal with the suppressor.
I went through this years back.. at the end, it doesnt matter![]()
For just the velocity aspect: Ballistics By The Inch

YOU are the first responder. Police, fire and medical are SECOND responders.
When seconds count, the police are mere minutes away...
Gun registration is gun confiscation in slow motion.

That's what I was thinking, not trying to build a coyote/prairie dog gun or a cmp service rifle shooter..

OK, trying to get an idea of a good trade off as far as muzzle weight vs change in accuracy. Thinking that the weight savings of a thinner barrel equaling the weight of the added suppressor.
Also, is there any reading anywhere on determining a good balance point for an AR? Such as if your front end weighs X number of pounds that you should be looking for a buttstock around X number of pounds?
Just want to build it as close to being right the 1st time that I can.
Thanks!
If you're talking about pinning and welding, it's not bad. It's better than the multi-point welding of "at least 3/4 of the radius" or whatever. I drilled a hole sized for a short cut-off section of shirt hanger. Countersunk the "pin" a bit so I could drill slightly oversized the hole the pin went into, then had the area welded a bit. I don't weld, so I had it done by those who I depend on for skills I don't have. I do a lot of stuff, with a lot of skills, but a man's got to know his limitations. The cheap oxy/acetylene kit at the local lowes won't do the trick, trust me, don't even try it.
You know someone that welds, that's your guy. BTW, soldering, etc, is not legal for this. It has to be welded.

14.5" for targets inside of 200 yds, and 20" out to 600 yds. For everything else, go with a bolt gun.
