Put simply, longer is more reliable.
Longer is also generally more accurate at farther distances.
He's asking about the gas system length not barrel length, though.
To add what EvilGenius said, the longer the gas system, the softer it shoots.
For a 16" I'd recommend a mid-length system. For an 18", I'd go rifle length (there mid-length is also available).
Thanks guys. I'm trying to learn the whole gas system thing. My other guns use more simplified systems, bolt, blowback and revolver.
You'll hear people mention stuff like; Dwell Time, Over gassing, Under gassing, Gas port re-sizing, H Buffer, F/A & S/A Bolt Carrier, "pig-tail" gas tube and Gas Piston.
You'll inevitably get into other stuff like Chro-moly, Stainless Steel, Cold-Hammer Forged, Chrome-lined and Non-Chrome-Lined, Barrel Twist, Chamber, Barrel Length and Barrel Contour as well.
Direct Impingement is pretty simple, actually, with very few moving parts. As long as you stick with a reputable brand it should be fine. It will comes down to what you what to build (varmint, bench gun, competition, range toy, erc...) how much you want to pay and what's actually available. Most everything else will fall into place.
Good luck on the BCG. Im striking out all over
Try Windham Weaponry.
EDIT: They have some parts, but not enough to assemble the entire BCG.
Luckily for me, I'm about two months behind the panic "wave". In January every one went out and bought out all the lowers. Now lowers can be found but the upper parts needed to complete all the panic builds have disappeared. I'm hoping that by the time I get my lower assembled, the production of upper parts will catch up with demand.
This is a good site for finding parts,
[Don't mention Large Cap Mag bans in the "tacticool" thread, that's thin ice on ADVrider. Might get pruned. :eek1 ]
Let's keep the politics out of here, please. :dog
The mods need to chill on that. But it's not my house and it's not my rules. Odd about what you can and cannot talk about in a EBR and "tacticool" thread. :huh
The general rule in any gun thread here is to leave politics and political references out. Because if they don't it inevitably devolves into a bitch/troll fest and slap fight between the the pros and the antis.This way the threads stay open and on topic.
If you need to voice a specific opinion one way or the other CS&M is down the hall.
You mean like facts, and laws,and legality of ownership?
I know what you mean. At this point this whole thread is a political statement.
palmetto state armory has uppers in stock
Site crashed...wonder if it was from everybody trying to buy the .22LR they got in.
Is $450 good for a S&W 15-22? I was thinking about getting a .22 for plinking, and saw it at the PX...
The mods need to chill? Do you even know who they are?
I think so. Ammo will be the trick.
ADV doesn't give it's mods a title that's obvious, so you've got see them modding others and remember. I'm not trolling for a finger wave or ban, I like ADV. It's just how things are here. Same with my comment above--not my house, not my rules. I just have to keep in my lane about which gun-topics on the board are politics verboten, that's all. I have no wish to continue a derail on EBRs and tacticoolness.
As for PX, that's a fair price. I doubt their pricing structure allows for max-profits (gouging) just as it doesn't always allow for lowest-price possible. The reports on the M&P 15-22 that I've read have been generall positive as well. I have a .22 LR conversion for my standard upper, but I think the dedicated .22 is a better option given the potential for leading gas tubes (and that the twist rate and bore diameter isn't right either).
I've been knocking around turning my 16" upper into a dedicated .22 upper (ie, tube fouling be damned) which *could* be used as a backup .223/5.56 upper. This would then allow me to justify getting a 14.5" upper with permanent FH.
You won't find a 15-22 any cheaper then that. Walmart sells them for $449. I love mine but like they said ammo is tough to come by in the current market.
