Ive got a new BCM 16" Recce upper on a BCM lower and BCM BCG. The rifle works great. How ever it seems to shoot to the left. Ive got troy folding battle sighs on it. At first thought it could be a defect in te sights, sent them back. Troy said the front was a little off but they sent me a new one, however i took it back out and im still 20 clicks to the right. Has anyone had any kind of problems with a BCM upper and troy sights

What forend do you have. If its not aligned it can cause more windage clicks.

It could be you. Have someone else shoot it.

Its not bolted to the receiver. Its bolted to a ring between the barrel nut and receiver. Its possible it could have been tightened down more to one side than the other resulting in a slightly crooked rail. Take everything off your receiver and handguard and look down it to see if its crooked.
If its not that, it could be a bent barrel or badly off center receiver face.

well, nevermind one that. I doubt it's the sights. Can you check level on the rail?

It's possible the face of your lower is not square to the bore the barrel goes into. A small piece of dirt or a burr in the area where the barrel meets the lower can also cause your problem.
Good luck with it.

I hope I don't come off as an idiot saying this but what would be wrong with adjusting your sights and calling it a day? I guess if you were mounting a PEQ or something of that sort but you could just zero that as well.

No, you are not an idiot.

Look, OP, guns shoot this way or that. Yes, you can investigate and eventually maybe find the cause, but when you have had the experience of years you will find that it happens.

You adjust your sights and move on.

IF you can shoot, and let's assume you can, it is not unusual or odd or "wrong" that a gun shoots this way or that. Many of my rifles are not middle-of-sight-setting "on" and the rear sight on my Smith M&P15 is set to the left of center and I've killed 18 ground squirrels with it in the last week {a small, tough target}.

Go back to the range, shoot, and zero, and then, Don't Worry; Be Happy.

i know rifles can all shoot different, ive been shooting before i went to grade school. my main question is whether or not any one has had a experiances with a BCM recce upper shooting more to the left. i know BCM will take care of me if there is a problem. just trying to see if anyone else has had an issue before.

Upper shouldn't be doing that.

Measure the gap between the left and right most rail, and the barrel. This will let you know if its square. Otherwise, your sights will be on a different axis than your barrel, and it will cause what you are describing.

My guess is your rail is slightly canted to the left or right.

Also, what muzzle device is on there? Did you put it on?

Sights are made to be adjusted, but 20 clicks is pretty extreme. That is almost the entire adjustment range to one side, and if you had to adjust it any more for wind conditions or variations in ammo, you would nearly be out of adjustment. A new rifle or upper should not require that much adjustment.

In the past, many people would put up with that type of offset because on other firearms there was no way to adjust it except with the sights. In this case, if it is something as simple as a misaligned part, there is no reason not to ask about it and get it fixed. Especially from a company that claims to be one of the best, using premium parts.

Check to make sure your sights are fully attached and aligned. There have been reports, in the past, of the Troy sights not sitting completely flush with the rail and being canted one way or another.

As mentioned above, my #1 suspect would be rail position.
With that many clicks of windage you should be able to measure the gaps between the barrel and the handguard and see a difference.

Sounds like the rail is misaligned.

I recently bought my first ar15 which is a bcm 14.5 upper. It shot to the left slightly and when I adjust my sights accordingly I was able to shoot straight.

One thing I noticed was that everytime I went to the range to shoot I had to readjust my sights because it kept moving back to the right. Eventually It started shooting nearly straight with sights adjusted almost straight down the middle. It could either be that i was becoming a better shot or that simply my rifle was still breaking in.

Hope this helps and Goodluck!
