Why does my gun shoot to the right?

[ghillie24]

Hello, I have an mp-001 with a tight bore barrel. I have checked my hop up, and I can't figure out why it doesn't shoot straight.

Are you using fine high quality bbs? It is important with TBBs to do such. Other possibilities would be that part of the bucking might have gotten bunched up at time of installation of the TBB. Some times, just taking the hop up completely apart again, then putting it back together is all it takes.

Other possible issues might include the end cap not quite aligning with the barrel, and it may be effecting the bbs as they pass by.

So my suggestion, check the hop-up, bucking, and to be safe, clean your barrel, and if that still doesnt help, try testing if it is the end cap. Test by taking the cap off and see if it shoots any better.

What is the end cap? I have already taken apart the hop up multiple times trying to fix it.

[T6e9a]

I may have assumed wrong, but I was under the assumption that there was almost like a sniper rifles' flash hider, it should screw on to the end of the barrel at the muzzle.

[ghillie24]

Yeah, that is already gone.

Check inner barrel for any obstructions or dents.

Also, do you have barrel spacers?

[ghillie24]

There are no obstructions or bends and I have no barrel spacers.

Ok, well, if you dont have any barrel spacers or any way of centering/stabilizing the barrel, it might shoot off to a side or other things of that sort.
My suggestion is to make some rings that can fit snugly around the barrel, and snugly inside the outer barrel. Foam would be optimum for this sort of thing. And you could wrap the whole length of the barrel, or do a minimum of at least 2, about an 0.5" to 1" wide, and space them out over the length of your barrel, and one at the very end would help to keep it centered, as long as you secure it, and it is nice and snug.

Have you tried holding the barrel up to the light to see how the intrusion of the bucking looks? Assuming a standard bucking it should look like like a small circle coming into the barrel here's a pic. If it is even slightly off it will cause your BBs to fly in one direction or another. Also you need to double check that the hop up is perfectly vertical when installed in the gun. Any other problem would likely cause just general inaccuracy. Unfortunately, I have no MP001 specific advice to give.

Also, it could be that your hopup arm need shimmed, or the plastic nub on the hopup arm is a hair larger on one side. The Mp001 uses a VSR hopup, and thats a VERY VERY common issue, cause the hopup adjuster is just a slider, and has a little l shaped part that slides into the hopup arm to adjust it.

Most of us on the sniper forums do a TDC mod. Thats a Top Dead Center. What that means is, you take off the terrible slider adjuster, drill a hole on top of the outer barrel, and insert a screw. This puts pressure evenly on the hopup arm and corrects the infamous right curve. I will go get the link to that mod on the sniper forums for ya buddy.
