Shot Grouping Issue
 

For some reason me BB's and shooting to the right with my M16. I know it is not my shooting technique and it was shooting straight and suddenly started to shoot to the right one day. Any ideas?

odd have you been lubing your BBs or has the hop up rubber been tampered with in anyway?

Did you bend the barrel slightly by accident without knowing?

Did you or anyone else remove the hop up unit in any way?

If not, adjust your sight to the right to make your barrel move to the left.

Could very well be that your barrel is dirty, so head down to your nearest Canadian Tire and pick up a Hoppe's cleaning kit, make sure it has the .22cal attachment with it ($8), and also buy a pack of .22cal cleaning patches (100 for $2-3) and have some silicon oil on hand as well. Fold the patch in 3, thread through the .22 cal head for the cleaning rod, twist in the direction the rod tightens, on the outside of the patch put a drop each side of silly oil, then twist through your barrel. Twist it while moving your rod Up & down, then pull out and run a clean (no oil) patch through it. Once done, try shooting your groups againand see if that helped. Then post back here your findings. If no one else helps, I will.

Well I did change the Hop-up Sleeve and Bucking a while back.

That'll do something. Might be that your inner barrel/hop up sleeve is canted to the right. Crack it open, try installing it agian paying attention to the way it slides in making sure the bottom of the hop up sleeve is in line with the bottom of the barrel and try again. Who knows, this simple fix might help you out 100%. If not, post your results and we can help you again.

Did you have a problem immediately after the change? If not, then it's probably not directly resulting from changing. Did you clean your barrel shortly before the problem started? Sometimes people twist their barrels out of its vertical alignment during cleaning if they use too much cloth/tissue and force. You might want to try giving your rifle a cleaning, twisting the cleaning rod only to the left during the operation and firing afterwards to see if things changed. If it has, you probably should dissamble your barrel and hop up and reassemble it.

Ok, I just took off my Hop-up and cleaned the barrel and put every thing back on. After testing I found that it still shoots to the right. Well I will be upgrading my gun with the following upgrades within the next three weeks:

-G&P Metal Body
-Systema Brass 6.04mm barrel
-Metal Bushings
-M110 Spring

If you guys can think of anything other than moving my back sight over all the way to the left let me know. I am hoping that if you guys cannot think of anything my upgrade will fix the problem but I will keep you guys informed.
