i am new to ars, just got a bushy m4 lookalike. any advice on cleaning? it has a crome lined barrel so does that mean i will not need to use copper solvent? do i need to clean the gas tube? will "gun scrubber" ruin the finish? any advice is appreciated. thanks, erik

First, welcome to the board.:welcome:

Second, congrats on buying a Bushmaster!:cool: I have one of their M-4's with the Y-comp "loudener.":D It's a great carbine, but a little hard on the ears (mainly the ears of anyone that stands near you fortunately:p )

As for cleaning follow the instructions in your manual for field stripping, clean the bore from the receiver end with a good powder solvent (I use Hoppe's #9), and that's about it for a chrome lined bore (you can always follow the solvent up with a light coat of CLP, but don't bother with a lot just a drop or two on a patch - I find that a bit of Breakfree CLP tends to get that last bit of crud out after using the solvent). Take the Bolt carrier apart and clean the various components and give the whole shebang a good coat of lubricant when your done (once again I use Breakfree). Clean the powder residue out of the receivers and then lube (AR's like lube). As for cleaning the gas tube this is not necessary from what I understand, nor have I ever bothered to do so.

Gun scrubber won't harm anything but if you don't get it all off it'll make your finish look more gray than black. No big deal just wipe down the areas you used it at with CLP and it'll return to that classy basic black

:) Hope this is helpful to you.

A shot of CLP down the gas tube from inside the upper just before scrubbing the barrel will dissolve all the fouling that builds up in the tube/gas ports. The first time you fire the rifle, the remaining CLP that is still in the tube that didn't flow into the barrel will be blown into the gas chamber and out of the tube/gas ports


If you practice this, when the rifle sits for years, the gas tube/gas port fouling will not caked/dry up with carbon/brass fouling and cause problems (lack of gas pressure threw the tube) when you pull the rifle back out years latter.

Dano, if thats what you want to do, fine, but I would not suggest a "shot of CLP" down the gas tube. The thing is stainless steel, and every time you fire the rifle it has some very hot gas under some real pressure that runs down it. Just leave the thing alone, nothing is going to build up inside it, either while firing or while in storage.;)
