AR help, please

[Hazcat]

Dudes and Dudettes,

As many of you know I cam into possesion of an AR a while back.  Well I am thinking of doing exactly opposite of what most of y'all do.  

I want to take it back to 'basic'.  All the way back to the old triangle handguards!

Here are a couple of pics of it 'as is'. (BTW the dates on the pics are not right.  fresh batteries and too lazy to correct the date )





It is a 16 bbl not including flash suppessor.  Notice that the front site is WAAAAAAY back from the muzzle.  The gas tube ends in the site.  What do I do to move the site (it has pins through it so I am pretty sure that it how to lossen it)  But what do I do with the tube AND any one have some ouls school handguards?

Reason I want to move it is the gun has the bayonette lug and it is useless that far back.

OH...it is a Bushmaster upper.

This is a hog hunting gun for mini-Haz isn't it?

I ran into this getting a replacement foreend for one of mine. You will need a new barrel if you want to move the sight - which also doubles as the gas block. This rifle has a carbine or mid-gas block. IIRC the original A1/A2 has a rifle gas block farther forward on the barrel. You're right that the pins (they come out left to right BTW) will remove the sight. It helps to have the Brownell's organge plastic sight replacement tool too.

Ya mean I can't lenghten the gas tube or place a gas block were the site is now?

Best thing you could ever do is just send the damned thing to me.
It'd free your troubled mind on this issue, before it ever gets out of control.

There is a hole under the site for the operating gas to bleed off to the gas tube, for the work and expense you would go to you might as well just buy a new upper.

Sorry but new upper is not in the financial cards right now.

I can't believe they don't make a gas block that can be placed there and just move the sight forward.  I thought you guys said the AR was Like a tinker toy!

I knew that Tom.  I just thought someone would have built a 'bolt on' for this.

Even if that COULD be done it would not fit under the retro hand guards, which may not fit on a 16 inch barrel anyway.

The original CAR 15 had round hand guards just like the ones you've got, the triangular ones were on the 20 inch barrel. So if you want to go back to the original AR 15 /M16 A1 you need a new barrel anyway.
