New AR - A Bit Different

JKP

My Dad recently gave me an AR that was built by my late Uncle. It's rather unique and I'm looking forward to trying it out as it's been a safe queen for far too long.

Some specs:

• Colt Match HBAR lower with a really nice trigger of unknown origin
• A2 stock
• Upper of unknown origin with a monolithic full length scope mount riser
• Bronze / yellowish bolt
• Massive 1.1" diameter DPMS 1:9 twist 16" barrel with an equally massive gas block
• Older Leatherwood ART 3-9x scope - not sure of model

The scope is the biggest unknown at this point. Supposedly popular during Vietnam, it's definitely different in that the range knob actually raises and lowers the rear of the scope. If anyone knows how these things work or has some experience with one I'm all ears.

Looking forward to running some 55-60 grain 223 through it.

That things looks like it is ready to do some serious shootin.

That HBAR looks a LOT like my Colt HBAR I bought in the early 1990s, difference being the gas block. That scope is interesting; never seen one quite like it. The scope appears to be an early Leatherwood scope, and mates with the Leatherwood mounting system on the rifle.

Here's the current Leatherwood scope and mount setup.

Looks like a DPMS Upper.

Neat family heirloom 
Looking forward to hearing how it shoots

Not sure it's in the heirloom group! 

Another gun that came home with me might be more suited for that (blasphemy to even place it on the Glock mat I know):

Nice. Both of them.

The gas block looks a lot like the one on my heavy barrel R-guns AR. Well, from what I recall anyways since I haven't pulled the dammed thing out of the safe in a few years.

Looks like it ought to work....whats that thing weigh?

10 lbs 9 oz unloaded. Barrel is THICK. The current offering from DPMS in a bull barrel is 0.92" in while this beast is 1.1".

Pretty cool!  I bet that's a shooter

Put some rounds downrange today. The scope functions as advertised - you can dial in elevation very quickly and it's relatively precise for what it is. Torso sized targets would be in trouble at varying distances.

That said, I'll very likely put some different glass on the rifle as I'm not all that interested in minute of torso elevation accuracy and have no plans to hit the battlefield soon. The monolithic riser in the upper will make scope mounting interesting.

That riser will allow you to use low rings, provided the scope will fit between the front and rear of the riser. Might have to go to medium height depending on the scope. I have one rifle with that high riser on the upper. It wears a low power scope, 1.5-4.5X, and no big honkin' bell in front made it fit like a glove with low scope mounts.

With that riser if you don't use low mounts you're gonna need a thick pad or spacer on the butt stock to get your eyes up level with the scope and your cheek supported. Other wise I really like it. With a good scope set up you should be able to put em all in one hole with that dude.

Looks like a tailor made p-dog rig.  I am sure it is fun to shoot... congrats!

Do you have the tools to get rid of that upper (stripped)? Never got that concept of an integral high rise on an AR. They are lego's, should be nothing permanent.

Yes but I don't want to invest the time to do it. Should be fine with some low rings and won't sit much higher than a scope in one of the popular one piece mounts.

 Cool. Nothing you can't overcome, especially as a pass-down piece!

Any mounting tips other than low rings?

 I guess they just don't fit me. Thus my statement. Not saying they don't have their place, just don't like the permanent nature when there are so many "plug and play" options available.

Went inexpensive (not cheap) and picked a Nikon P223 3-9x scope and Leupold Rifleman low rings. Better to be lucky than good - barely fits with the low rings. 

Will see how it shoots soon.
