Tight Bores and Sniping
 

I would have thought that airsoft rifles were more accurate than they actually are, especially in a snipers perspective. Right now I have an Echo1 ER25K, with the mock silencer installed. So at this point I'm wondering how much of a precision difference a tight bore would make seeing that my mock silencer is close about 11" long, and I would have around 600mm of tight bore barrel length from silencer tip to hop up unit. Will a tight bore make a big difference?

Stock guns are poorly inaccurate regardless if they look like real world sniper weapons or not. If you want a hyper accurate AEG that can out shoot snipers you'll NEED a good tightbore, high quality hopup rubber, Upgraded Nozzle (more stable airflow pushing the bb) and mostlikely a better hopup unit. And last but not least, never shoot anything lighter than .28 bbs, I stick to .3s for accuracy.

And use BB Bastards. Best BBs in the world. Cannot recommend them enough.

Yeah I ordered some .28g bbs. I didn't think .3g bbs were right for a 400fps @ .20g bb. I guess I will get myself a good tight bore, because the accuracy of my AEG is relatively good for one that is completely stock. I haven't found any mock silencers that are longer than the one I have so I guess I'll stick with it so I can have the longest tight bore possible. The tight bore seems to be the most important part for long range accuracy so I will start with upgrading that.

Want a laugh? Take your 400fps @ 0.20g and use 0.36g BBs, come out at around 300fps. This combo became the majic combo for me the last few years I played airsoft with my CA M24 (397fps w/0.20g). Sure you gotta adjust for elevation like real steel, but the consistancy and range is awesome! Airsoft sniping is all about watching your round make it's way through shit, adjusting to compensate for shit, and squeaking the round through gaps in cover to really screw with people. Long range shots are bullshit to go for, hard to be consistant with a 6mm BB flying through a variable fluid, and honestly, anyone can sit 300ft+ away and fling BBs. Getting in close and pushing a round through a 2" gap in a wall of a base from 150ft away, now that is the ultimate in airsoft sniping, the stuff legends are made of!!

BTW, what are your thoughts on using 0.30g or 0.36g BBs in your GBB? ;)

No, some stock guns have great accuracy.

True, But I was more trying to make the point that a replica of a semi auto sniper rifle is no more accurate than a replica of a regular infantry rifle

I just placed another order with evike (vest, extra mags, .28g bbs), at some point I'll definitely try .3g, but right now, I can't find a local retailer or even from another province that seem to have quality upgrade parts... Or am I just looking at the wrong place?

This is my gun

Look to Asia. There aren't too many companies making tightbores in 600 mm lengths, and those that do are making them for a specific type of gun (AK, M14, PSG, etcl) . Most are making them in the 300-500 mm lengths.

I see some 500+mm tightbores that are sold from torontoairsoft, but are the ones they are selling any good? Also I'm not sure what to look for when refering to hop up rubber. I believe echo1 have some pretty decent stock hop ups, unless someone says different.

You want an accurate gun, and you bought an echo1? lol

1) length of barrel means very little, stay between 380 and 500mm
2) actual bore of the barrel means very little, stay between 6.03 and 6.08
3) hop up rubber is EVERYTHING when it comes to range and accuracy. Get a firefly hard rubber with the firefly nub, will have a huge impact on range and accuracy
4) Use the right weight of BB for FPS. >380fps=.30g >440FPS=.36g >490fps=.43g
5) Make sure your airseal is PERFECT. You'll need a perfect airseal in order to get a laminar airflow down the barrel to guide the BB. Too long of a barrel increases the chance of the BB hitting dirt inside the barrel or losing pressure behind the BB.
6) Make sure your cylinder has enough air volume to push the BB out the barrel, loss of pressure and laminar flow means loss of accuracy
7) Get a proper platform for the task at hand. You don't substitute a glock18c for an M249, so why substitute a sniper rifle with an automatic rifle?
8) For accuracy and range, nothing beats a bolt action rifle. Higher quality components, better sealing, way higher repeatability over AEGs

9) If you want a REALLY accurate and long range M4 variant, and it HAS to be an M4 variant, get a GBBR. Weather permitting, gas guns are more accurate and have better range than AEGs. There's huge posts on it, but basically the BB is better stabilized faster by high pressure gas than by low pressure air.
If you have the money you could also buy a PTW lol

I disagree with a GBBR as a superior sniper gun platform (unless you convert to an HPA rig). In my experience, there is too much variance in gas pressure to make your shots consistent. You may get the range (assuming your hop up is not contaminated with the oil in the gas), but you won't get the accuracy over AEG and definitely not over a bolt action springer.

If you want the ultimate sniper gun platform, go with a good bolt action springer (like Maruzen or TM) and properly upgrade it to the power and range you desire. When I say properly, I mean don't leave any weak spots. Don't just change the spring and leave everything else stock. Everything must be upgraded to the same spec simultaneously. Be prepared to shell out $$$ if you want the most accurate and long range.

And I wouldn't go so far to say that the size of the tightbore matters little. It matters quite a bit. If you go too big, you will lose your laminar flow and get turbulence instead. I would go with 6.03mm.

It's actually been long accepted in the BASR world that tightbore barrels increase FPS over a standard bore rifle and that a 6.08mm actually gives better shot-to-shot consistency over a 6.01mm barrel of identical lengths.

Can someone tell me where I can get this bucking and nub?

??

What bucking and nub? There are a lot of different buckings and nubs.

firefly, most airsoft retailers, but they're highly sought after, they're usually out of stock.
Based on real world airsoft experience, it's the consistency of the bore that makes all the difference.
Some pistols are highly accurate out to 200 feet, some long barreled AEGs are not.

And like I said, WEATHER PERMITTING, a GBBR is a better accuracy platform than an AEG.
not a pistol
NOT a gas bolt rifle
not an SMG
a GBBR

There's a lot of physics behind it, but bottom line, you throw .43s in a KJ M4 and it's a ridiculously awesome DMR

Right, so I'll need a bucking depending on my barrel right? (6.01, 6.03, etc...) I found some retailers that have the bucking, but when I try to search for nubs, I come up with nothing found. I've tried going through all hopup categories, and still haven't found a nub on a retail site. Is there a variation to how a nub may be called?

Buckings usually come with the associated nub, some real specialty ones can be bought separately. And they aren't barrel ID specific either.....

no, you'll need a bucking based on the barrel DESIGN (VSR, regular AEG, PTW), and your FPS
low fps = soft rubber
high fps = hard rubber

Stealth, have you ever heard of the ORGA wide bore barrels? The barrels are really wide, like 6.23mm. That's like .15mm larger than a standard stock TM 6.08. They're made in Japan too so theoretically have high tolerances for the trueness of the barrel. Sounds like a lot of marketing who ha for their descriptions of the benefits and stuff but it might be cool to try out (also apparently due to advertising laws in Japan they can't make super outlandish claims but I'm not sure if this is true or not).

Listen to ThunderCactus and CDN_Stalker on this one. They know the sniping game well.

Try a firefly bucking!

As far as barrels go, length can affect your shot. But as to how long versus FPS, rounds, etc has been a very difficult point of contention between airsofters. The most all around stable barrel you can get is the 6.04. If you want to increas your grouping a little, try a 6.03 but go no tighter. After that, you are very realistically only increasing FPS and BB destabilization. Some guns will use a 6.01 well, but I haven't seem many. For a longer range/accuracy, stay between 6.04/6.03.

Right, I was thinking AEG..... then again my CA M24 uses AEG rubbers. :D

p* engine or hpa-converted bolt-action with an er-hop, an lrb and a 6.03mm inner barrel. it ought to do the trick. super-heavyweight ammo goes without saying, of course.

I'll just leave this here...

The 8mm bb is whole new world for airsoft snipers

8mm BB's aren't a new thing. Marushin was the first to do it (and they're an old school company). Just saying....

BB Bastard is posturing to release their new round (if they haven't already). It's a 0.66g round, in 6mm standard BB. That ought to put some holes in stuff.

Never liked 8mm rounds, too much air resistance, too large a profile to deal with wind effectively, less mass for the size two (played around with them in a shotgun years ago, the 0.46g felt lighter than the 6mm 0.43g), etc. That rifle as sweet, as it is, only has an effective range of 50m, many 6mm rifles have an effective range past 75m, and will retain more energy too.

Agreed, 8mm is way too big
maybe if we had 6joule limits, we'd get enough velocity out of them to be of use, but with the size of the round they just fly too slow, and no aftermarket companies make quality 8mm barrels or high grade 8mm hop rubbers

Why is it the only place where I find firefly buckings are from retailers situated in asia... Are there any equivalents to this bucking that I can possibly find in north america?

Because firefly doesn't make them fast enough to have stock oin north america
Like I said, HIGHLY SOUGHT AFTER, they're really high performance rubbers

However, I just put a falcon hop rubber in my 249, since all I could get my hands on was a falcon 6.03 barrel for coldfront (and the barrel comes with a rubber). Just took it out last night and put 600 rounds through it, it's pretty damn good.

Um.

You have seen the X High Tech clone of the Firefly right? It's like $10.

Yeah I was going to make a reference to the big-bore barrels, but the name and exact diameter escaped me at the moment. I have no personal experience with them but can only imagine that they must have conducted numerous tests to settle on such a wild bore.

I've found that Trinity Airsoft seems to have them more often than most retailers, no idea why.

However they are still incredibly hard to come by

Get a firefly rubber from illusion if hes not too busy, i ordered mine from him a while ago
