It should work with a steel barrel just don't let it sit with the bend for long periods of time.

And that right there is the big question! You pretty much have to do every mod known to man and buy top of the line upgrades and have a little bit of luck. For those of you that can shoot that far and hit the target 7/10 times please chime in!

I still can't get my gun to reach out to 100 yards with a flat trajectory or at least semi flat. I can get the bb that far but only with a decent amount of over hop.

I too have a long range barrel on my VSR and I can only get Torso sized target about 50% of the time at 70 meters.
Personally I would have to see the extra long shots (That don't have excessive hopup) that are over 70m to believe it.
The LRB does work to stabilize (Helps with accuracy) the shot but I don't think it gives longer range.

huh.. Steel is stronger than aluminum, so shouldn't it be more resistant to the stress over time?

So I went ahead and did my attempt at the LRB mod.. I put a barrel spacer about 4 inches from the hop up chamber and another about 3 inches from the front of the barrel, then I measured and drilled/tapped a 1/4-20 screw hole in the center of the length of the barrel between the two barrel spacers and put in a 1/4-20 set screw to put the needed pressure on the top of the inner barrel. I will post updates on the performance when I can actually test it.

Thanks for the help on understanding the LRB mod I think I got a good compromise to the Flatline version of the LRB mod and I have the means to put the pressure where its needed to get the right bend in the barrel to allow the barrel to stabilize the bb.

Aureus, that actually goes for any barrel not just a steel barrel, which will be tough to bend...

Militantchicken, I don't know what you are doing...
You are suppose to have the screw on the bottom of the barrel not top if you are doing the LRB with the bend in the middle of the barrel like the flat line barrel.

If you do the other one then the screw needs to be on the top at the end.

So basically, with the LRB, it's advised to 'turn off' the pressure on the barrel if you don't plan on using the sniper rifle for long periods of time? That's gotta be pretty annoying to keep on adjusting the LRB every 3 months or so lol.

 

[TheHunter]

Yeah and you are suppose to do the same with your hop up.
It isn't that big of a pain. Once you find your sweet spot through testing just measure it and then remember to put it in that spot everytime. And then adjust your hop up to where you want it. It might take a couple min altogether.

True, oh yeah that explained why a r hop patch of mine for my Type96 was literally flat. I forgot to turn off the hop up and a few months later, it was useless lol.

Edit: I started on my LRB, following this guide. Unfortunately, the PVC pipe has such a tight diameter, I'm having trouble fitting it onto the outer barrel.. Hopefully i won't need to resort to heating the pipe and stretch it out..

Update: Excuse my messy desk ( doing so many airsoft related things at once here), but here's what I came up with. I tapped a hole about 3/4" from the tip, and jb welded a nut there. Then I cut the top off a soda bottle cap and hot glued the sides ( so it'll be a tighter fit) then jb weld the outside for a more solid foundation. Gonna sand it down when its done curing, then painting the entire thing. Thoughts?

 

[Dorekido]

I think that information need to update on post#1 for who want do this LRB mod for notice.

 

[TheHunter]

Aureus, it's looking good. Why didn't you put the nut inside the PVC so it doesn't stand out and use a set screw? Hopefully the hole is big enough for the barrel once it gets a slight bend in it. You did check right? Lol

I will have to use you coke can idea tho to cover up the end!

And maybe you can sand the barrel down a little?

Dorekido, what information are you talking about? Turning off the LRB?

Thanks. Its just a prototype. I put everything together to see how it'll look as a finished product. I still have like 12 inches of PVC pipe left so I'll be improving it. I'll try the nut on the inside for the next lrb . The only problem I have now is that I managed to get it onto the outer barrel, but its stuck. I can't push it in any further, nor can I pull it out..:doh:

 

[TheHunter]

Dang that's strange. What gun is this going on?

My UTG Shadow Ops /Type 96. I'm going to try the hair dryer to see if that can melt it a bit w/o burning. I'll resort to the stove as a last ditch effort ( times like these are when I wish I had a heat gun, then again, a dremel would be nice too)

 

[TheHunter]

That's weird that it is that tight on there. Hmm well hopefully you get it off.

Maybe you can cut a slit in it and then jb weld it back together?

Haha, na. That'll make it look weird.. also I don't have any 'precision' saw/cutting tools capable of going through 2/8" pvc material.. I'll end up mauling my outer barrel :/ I'm going to try spraying some silicone oil at the point where they contact each other and hopefully some of the oil leaks into the crevice and allow me to pull it off..

Update:
Well, since my r hop installation aid came and everything, I went and installed a patch onto my 509mm barrel ( still need a tiny bit more tuning) and I reinstalled the LRB mod ( I had to use my stove as a heat gun) W/o putting downward pressure ( basically pre-LRB mod) I was getting fliers every shot. I would be lucky to hit a target 5/10 times. However, after screwing the screw down 1-1.5mm, I was hitting my target 8/10 times. Basically, accuracy has been drastically improved, but its still being overhopped a tiny bit on my 0.43s ( the force of the overhop is making the bbs fly up vertically straight fight before it hits the target)

Time to go back to the drawing board and revise the 'looks' of the LRB/silencer. Btw, since you only have 1 barrel spacer, 70% of the barrel is HOLLOW. Keep this in mind, as the LRB will cause your gun to sound differently and most of the time, its for the worse than better. My advice would be to use memory foam and stuff it down before attaching the LRB ( yes, the same foam you would use to fill the air pockets in your stock, mainly for Type96 rifles)

Excuse the blue painters tape. The front body screw for the stock won't screw in ( possible stripped), so w/o something holding the outer barrel against the stock, I'll have feeding and magazine ejection issues.. I'm just waiting for my 550 paracord to arrive at my doorstep so I can make it look nicer

 

[TheHunter]

Well that sounds like it did pretty good.

If you put the next size up of PVC over your current piece it will thicken I up and make it look nicer and add about 3 inches.

Can't wait to hear about the final product

Thanks. I'll dig around to see if there's a bigger pvc pipe that fits over the current one. I wasn't too sure on the dual layered piping, as that may look too fat for my taste, but 1 layer isn't really noticeable.

 

[Aureus]

So... excuse this past-due post, but I need some help. I've tried this multiple times, but it keeps on failing. Basically after taking into account the advice from Hunter ( where you put the nut, for the 'silencer/LRB pipe, w/e you call it', inside the pipe so it looks smoother to the eye), I tried gluing it on with super glue and JB weld. Both won't stick for some reason. I used JB weld fine for the TDC mod ( outer barrel was metal), but apparently the JB weld doesn't like PVC.

Super glue doesn't work well since the nut is flat, but the piping is obviously round, so there's not much surface area for the glue to stick. How did everyone else get the dam nut to stick on the piping? Btw, ever since I removed the prototype and made a longer 'silencer', I think it looks a lot more legitimate now. I also still haven't solved the hollow "poom" sound for every shot. ( Its basically like getting a PVC pipe, covering 1 end with your hand and smacking the other end with your palm.)

 

[TheHunter]

Mine stuck just fine and I used jb weld. Try sanding the inside of the PVC to give it some grip. And your inner barrel should stick out to the end of the PVC so that the two are even. Then you won't have that funny noise. That's why I said put the nut like half an inch from the end of the PVC so the inner barrel and PVC line up.

Eh, I ended up jb welding it from the outside.. I only have like half an inch of free space in the PVC pipe, but since there's only 1 spacer for the inner barrel, the other 2/3s of the barrel assembly is practically hollow. Wait lol. I just had an epiphany ( literally while typing this.) I'm gonna grab some sponge tomorrow and tape it onto the inner barrel ( so its basically a pseudo barrel spacer) Should dampen the sound a bit, plus its squishy so it should conform with the LRB.

Thank god I didn't follow through with my original idea of getting wax and filling up the barrel ( would've rendered this LRB mod useless if the barrel can't bend...)
