The first and second ones look good ,but I'm not sure how the last one works.
Also, this one might work: http://www.airsplat.com/Items/AC-UPI-DF-CPB01.htm

Hes not asking for another website, he wants to know which one he should get from asgi, so that his friend can get free shipping.

I say go with JBU.

Sorry I forgot; I would pick the JBU because its the tightest, cheapest, and the company is trusted.

ok ill go thit the JBU and what kind of material should i wrap around the cleaning rod to clean the barrel after i instal it

I use gun cleaning patches, sized for .22 caliber.

and if i dont know what that is or cant get it i could use....

...a piece of soft paper towel

ok thats seems a bit more wallet friendly to lol

Is toilet paper okay to use (lol)?

It's a little too thin, and tends to leave little fibers in the barrel. It works in a pinch, but try to get something better.

Real steel gun cleaning patches are the best. Just make sure you don't put and solvent on it.....

Cotton is great to. Silk is soft but thin. Use scraps of old shirts.

and then spray some silicon oil on it?

Yep. The gun cleaning patches are basicly cotton I believe.

Yea, I have a gun cleaning patch that I lose a lot, and there is usually always toilet paper available. I'll just use the patch from now on. I would not advise spraying silicon oil in your barrel to clean it. Many swear by it, but it can really irritate accuracy. Yes, I know, you can shoot it out, but I just don't see it helping too much. But, some barrels can get pretty dirty, and sometimes just cloth won't due. So yea, spray it if you need to, but make sure you clean it or shoot it out. And for the love of god don't spray your hop up rubber, and if you do, just clean that (water, dawn, isop (atleast) 90% (preferably) alcohol).

well not according to asgi... scroll to the bottom.

When i lubed up my gun it worked just fine, but my friend tried it on his M14 and it worked like crap for 300-400 shots and then it was fine, but he used a lot of the silicone oil and i only used a very short brief spray. so from IMO I think that it matters really only how much you use, if you only use a little it will be fine, but using a lot won't help.

^Well said

@Hartwig. Lol, yea, I'd have to go and say I don't totally agree with them. But I'd take it in the context that tommy boy puts it. Also, it's important to not rip the hop up and not get the oil in the hop up.

Hey look, they used a KWA. I wonder why...
