I'm confused, is "vice" Ukraine for "versus"??? Please realize that when you join a forum and your very first posts are about a hypothetical problem that may or may not arise sometime down the road, the responses may not be what you are looking for.
The responses here are from microcephalic trolls who make themselves feel big by throwing out a flood of babble when a simple response of "no, it shouldn't be a problem" would suffice.
A proper response, from a much better website, is thus: "You could run into problems (especially rim lifts) using slower powders with heavy bullets. I use a +2 gas system on my 28" .223 spacegun using 75 gr bullets with N-550; even with an adjustable gas block there were problems. If you're shooting light bullets and powders at at the faster end of you may be OK."
The wanna-be tactical clowns here do not know as much as they think they know.
A professional response from a MN website and not the usual Sniper's Hide snipes and GED grads:
"Somebody please correct me if I'm wrong here but it looks like he did yours just like any other. It appears that he left the gas block journal long, as some blocks are longer than yours. But, the gas port is in the same location regardless of how long the block or the journal is, for a given system length.
As for ideal gas system length, bbl length, cartridge and powders/loads affect what's ideal and what's not, even with an adjustable gas block. For that reason, I think you need to talk to your smith. Sounds like he steered you right since it's working well and you mention no brass or cycling issues.
I've done a total of ONE 22 ARC AR15 build for someone. IIRC, it was a 20" bbl when done and I used a std rifle length system on it. The customer mentioned a +1 and I preferred a mid length, so the std was a compromise that we were both comfortable with and worked well. There are several ways to optimize gas, aside from gas system length and I seriously doubt you'll find any accuracy from the length that you can't tune the rest of the rifle to with the many possible things you can use to tune it with.
The one thing I'll say that I agree with is that you should be able to squeeze better accuracy from it, given top shelf components etc, likely with load work. But, IME, an AR that shoots CONSISTENTLY better than the low .3's at 100 is pretty rare. There are several factors working against BR accuracy in a functioning gas gun. That said, it's not a BR rifle and low .3's ain't shabby. I'm not talking your best groups, but consistently. Big difference there. There's also this thing that many, many people fail to fully acknowledge and that's wind..even at 100 yards. So, are you shooting over flags? If not, you'll never consistently shoot below the condition value."
"Wow. Thank you very much for such any excellent reply. Yes, it's not like I am taking 20 or 30 rounds and averaging the groups, heck, I do not even have 40 rounds thru the rifle yet. I can certainly live with .9 groups the rest of my life, but this is a coyote hunting rifle that will live mostly on a tripod. This is not a bench rig. .3 is way above my pay-grade and normal ability. I was shocked to see any .3 at 50 or 100 yds
I am thrilled with the initial trip to the range so far.
This is not a $3000+ money pit rifle.
I did put a JP full mass BCG in this 22ARC rifle and also a Lilja 204 Ruger .920 rifle too. Another shooter too thus far. The upper is nothing more than an Aero Enhanced GEN2 proprietary upper. Both rifles sport a Geissele 2-stage flat-bow trigger. Bolt maker? Can't remember right now.
I did thermal fit the Lilja 204 Ruger barrel myself into the same Aero upper, but the old gunsmith said that he did NOT have a thermal fit for the 22ARC barrel he made as I sent him the Aero upper to expedite things for me.
I do not reload. I usually shoot at a 100yd indoor range.
I have not had a desire or need to mess with buffer weights for more tuning.
Thanks for the answer and reassurance. Excellent."
