When I zeroed my 16" M4forgery this weekend, I found that I had to move the reticle to the left approximately to the second graduation on sight base. There are several more graduated marks to the left, but it still appears as if the reticle is canted off fairly far. Is this a normal amount or should I be looking at a possible issue with the rifle? |
Thanks for the link. Looks like the left leaning windage due to barrel torque may be at play, but it also looks like the fix could be expensive and in the end unnecessary if the gun is shooting straight with the sight adjustment. Not having worked with too many AR-15s, I guess I was just looking for some opinions about whether or not the amount of windage I needed to adjust my rifle is excessive or relatively normal. |

you don't look like you're too far off center. i'd prefer it to be closer but then again i've given more than one or two rifles the rubber mallet treatment. you still have plenty of adjustment room for windage changes, if you are happy with it, your gun looks to work fine as is. |
If you had the tools and experience you could attempt to work some of the excessive windage out. But, as long as the rifle zeroed fine and your rear sight is not completely maxed out against the stop, I’d let it go. |
That's the kicker. Right now I'm living in an area that doesn't afford me a shop of any kind. I think if I can keep it zeroed I'll live with it for now. Just for grins, any opinions on how much a gunsmith would charge to straighten' it out? |
A gun smith would probably charge you what it would cost you in tools to do the job your self. All that’s needed as far as specialty tools go is a receiver vice block and a barrel wrench.... about $60 in tools. If you plan on staying with AR’s and possibly building rifles in the future you might want to invest in the tooling. For now, keep the rifle as it is, then when the opportunity presents it self you can sit down and try to re-index your barrel. If you do not see the need for tooling in the future and the windage bothers you that much, find a local smith that does AR work. Or, ask in your Hometown Forum. Maybe someone local to you who has the tooling and experience can help you out. |
