Not been altered in any way. Serial is a CCH 002XXX. A few handling marks, but the bore and receiver are pristine.
Comes with 2 mags. I'll throw in a third mag as well as one of them needs the feed lips adjusted a little.
AR 15 , AR-15, however you want to spell it
We are very fortunate to live in WA state that allows a face to face private party transaction to be done without any paperwork required. No transfer, registrations etc are required. I only need assurance that you are a WA state resident and that you are legally allowed to purchase a firearm. That's it, no bills of sale, nothing else. Take advantage of our freedoms now before they change!
I'm near the freeway between Longview and Chehalis / Centralia.
Partial trade for a marine pump 12 gauge shotgun such as Winchester 1300 Coastal Marine, Remington 870 Marine Magnum or Mossberg 500/590 Mariner. I would have to have some cash on top as well obviously.

What is the manufacture date of a Colt AR15 model SP1 serial number SP192754?
What is the manufacture date of a Colt AR15 rifle serial number 192754 model SP1
When was your colt ar15 manufactured?
You will have to call Colt and tell them the serial number.
What year was the colt ar15 ser?
- Colt AR-15 SP1 carbine, model R6001. This is a pre-ban AR, serial number SP1687xx. We believe this one was made in the early 1980s. (All serial numbers below SP360200 are pre-ban).
- Newbie to this but how does one figure out when his rifle was manufactured if it is possible. Mine is a A2 SP 31805x and is supposed to be preban. That is, mine has 6 digits These are 5 digits prior written here Colt AR-15 Serial Number List.
- Dec 11, 2016 I don't know about the online database, but when I called them with the S/N of a Colt pre-ban AR-15, they were able to tell me the month and year it was built.
- I've heard some hypothesize that the CR is short for civilian rifle, some say it's short for colt rifle, others say commercial rifle. I don't pretend to know when or why colt has changed their serial numbers prefixes. I don't really care either.
Hi, I saw the thread which listed colt AR15 serial numbers, it seems to be the same one which is floating around in alot of places. I'm interested in buying a Colt Ar15-A3 Tactical Carbine model# 6721. Colt has been the most visible producer of ArmaLite AR-15 pattern weapons, and the military designations M16 & M4 are heavily associated with the company. Colt has an intricate internal nomenclature system for its models, with a variety of suffixes and prefixes. US Property marked XM16E1 Colt's and M16A1, both Colt Model 603. There are also a small number of US Air Force M16 Colt's Model 604 found in this serial number range. Serial numbers in this range were not run in order. M16A1’s have been observed with serial numbers as low as 604,505, and XM16E1’s have serial numbers as high as 741,12X.

1 - Colt built several thousand 'bastardized'AR-15's using different lower receivers but the same model number. Dependingon the date of manufacture it may have an A1 or an A2 lower receiver.There doesn't seem to be a definitive list of which rifles have which receiver,or when Colt began using strictly A2 receivers for their AR-15's.

Barrel contour/slip ring/handguard terms
Standard: Original thin barrelstyle. Did not stand up to prolonged firing very well giving reducedaccuracy.
A2: Later style of barrel that was tapered at the front sight to thicken theexposed barrel. Apparently to
strengthen the barrel to avoid bending when G.I.'s used it as a pry bar.
HBAR: Lateststyle of barrel that is the same thickness the enitre length through, ratherthan just the exposed
section. Stands up to heat well and gives better accuracy.
HBAR
stepped: New barrel for the M4 carbine designed specifically with a 'step' to accomodatethe M203 grenade
launcher.
Straight: Slip ringretainer between the handguard and the upper receiver that has a straightcylindrical shape.
Typically found only on early AR-15 and M-16 rifles with A1 upper receivers.
Tapered: Slip ring retainer between the handguard and the upper receiver that hasa slight conical shape. Used on
all new AR-15 and M-16 rifles.
Smooth
triangular: The original handguard usedon early AR-15 and M-16 rifles. Still commonly seen today, not usedon
newer rifles. The handguard is a smoothened triangle shape with vent holesat the top.
Ribbed
cylindrical:Newerhandguard used on all modern AR-15 and M-16 rifles. Cylindrical ratherthan triangular, it has
vertical ribs along the entire length of the handguard for better grip. Vent holes are along the top and
bottom.
Ribbed
shorty:Identicalto the Ribbed cylindrical handguard found on modern AR-15 and M-16 rifles,the shorty
handguard differs only by being shorter to accomodate shorter barrel lengths.

along its entire length.

possible. Has several holes in the top and bottom to accomodate specialattachments such as a vertical

prevent dust kickup when firing.
A2-style:LatestColt flash suppressor that has five openings (two to either side, two diagonallyupwards, and one up) and
a closedfront end. The lack of holes in thebottom of the suppressor avoids kicking up dust when firing.

four-pronged and 1/2' longer than the 3-prong suppressor. Newer modelshave the prongs twisted
slightly counterclockwise.
