Yes, I'm the official AR15 idiot for the day. I just finished replacing an A2 upper with an A3 and mounting a Leupy VX3. I headed off to the range only to realize that I was shooting a straight pull bolt action.

Well I got the scope dialed in but when I got home I had to remove it to take the gas tube out and twist it so the hole was facing the barrel.

I'm using the RRA 1 piece scope mount that screws on with thumbscrews. Will I be way off when I head back to the range next week?

Put it on in the same spot on your rails. It will be a little off but not too much.

Why do I find this so hard to believe.

A long time ago I was sitting in an armorer course, with zero sleep and no coffee. I put the tube in upside down, and sat there looking at it for a minute. I finally snapped out of my lack-O-coffee coma, slapped it back together, and laughed at myself.

It happens sometimes.

When I started shooting I was like shit, a fte after the first round. Then the same thing for the 5 rds I had in the mag. It wasn't until the 4th or 5th round that I realized that I wasn't hearing the buffer spoing that I usually do.

The whole drive home I was hoping that it was the gas tube and sure enough it was.

As to the scope, I always mount it as far as possible on the upper and even then it's about 1/2" too close.

Well, I've seen people do dumber things on here (think underwater bumpfiring to see what would happen.)

At least it will work next time, unlike Mr. WaterBump

A gas tube has close to 3/16" offset in it. Rolled the wrong way it is off almost 3/8". It puts the tube so far off you would have to use a lot of force to get it in the sight base on that kind of angle and then try to align the other end where ever it wound up pointing. I just tried to do it and gave up when forcing it in the sight base. How come it is so easy for other to do this?

I am I doing something wrong trying to do it wrong?

You have to ask a question like that?

When I was in the Army I was a 45B,Small Arms Repair.At the end of my AIT I had to inspect,repair and test fire several weapons.When I got to the M16.I was instructed that there would be nothing wrong with the upper receiver assembly.After repairing it we headed to the test range.When I pulled the trigger on the first round I heard and felt something wrong.I don't know who worked on it before I got it but the gas tube was upside down.SJR556.

i bought an AR-15 about 5-6 years ago that only fired a single round at a time.., paid $500 for it, a preban.., took it home removed the H.G. & sure as hell, the tube was installed inverted, reinstalled, shot it for a year, then sold it for $1,200 just before the ban ended.
