What you have is the civilian version of the M16A2.
It is a full length rifle with 20" barrel, solid stock (not a short stock) with the A-2 sights (Windage & Elevation adjustable rear sight).
The bulk of Marine & Army rifle companies are still issued this rifle, so anyone that wanted a authentic (but semi-auto and legal to own) version of those rifles would be interested in it.
Originally a Subsidiary of Fairchild Aircraft, Arma-Lite is the company that Invented the AR series of rifles, designed by one of the worlds most brilliant gun designers, Eugene Stoner.
Eugene Stoner is one of the big 5,
1. John Moses Browning
2. Benjamin Tyler Henry
3. Samuel Colt
4. Eugene Stoner
5. Mikhail Kalashnikov
And even though the company has been sold a couple of times, Arma-Lite still makes one of the finest examples of rifles made.
The company now makes it's home in Geneseo, IL. At exit 19 just north of I-80 in Illinois.
Ball park estimates would run as follows from what I've seen at local gun shows lately...
Between $750 and $1,000 if it's in 'Like New' condition with out the box or original factory paperwork.
VG or Very Good condition (minor wear from firing, but still pretty much new condition) will still bring $500 to $750, maybe more, with out box or paperwork in the correct situations.
New 'No Name' AR's are bringing $750 to $1,000 for no apparent reason I can see, and brand names, (Colt, Arma-Lite, ect.) are bringing $1,500 to $1,700...
AR-15 anything is going for outrageous prices right now...
I saw some pretty beat up examples at the gun show going for way more than I'd ever pay for them, and some were obviously pieced together going for new price!
I have no idea what's going on with the market right now...
Must be scared, xenophobic christians buying in record numbers because of the 9-11 thing and the crap going on in the middle east...
I just sold a run of the mill AR, noting special, just parts I'd taken off customers guns with a generic lower receiver, and I was asking $450 for it, but didn't have a price tag on it.
Good little shooter, but nothing special...
The three guys started trying to trump each other in front of the display booth at a gun show, and I wound up with almost a grand out of it and a half dozen magazines...!!!
