My first AR-15 was an M16A1 in active Army from 1974 to 1977 (and 1977 to 1979 in the Reserves). My second and third ARs were USAF GAU-5/A/A (11.5" bbl) and GAU-5/P (14.5" bbl) in 1979 to 1981.

My first personally owned AR was an SP1 20" in 1982, which I traded for a Colt SP1 Carbine in 1987. I had that until I was forced out on disability in 2000.

Also, between 1988 and today, I have built dozens of the little erector set guns in all configurations on PWA, SGW, Palmetto, Essential Arms, DPMS, Eagle Arms, Sendra, Stag, Anderson, JD Machine, and Smith & Wesson lowers.

While I currently have several home built ARs on various lowers, I decided I wanted another "Real Colt" AR-15.

It started when I was arranging the purchase of a OEM1 stripped Colt 6920 M4 for a customer of the shop I worked at. The Appendix B prohibits Colt 6920 "Law Enforcement," but not "M4". While the customer got cold feet, I contacted Aaron at Ratworx, He switched the 6920 lower for a 6933 lower, marked only "Colt Carbine" (which is not on the banned list which lists only 6920). We have DROSed Colt Carbine marked 6933 lowers at the shop before with no problems. He is shipping me the upper, so the receiver only is going top the shop.

While the originaL customer got squeamish and backed out, I decided to go ahead with the deal for myself.

While I have lots of black rifles, it will be nice to have a Colt again. My GAU-5/A/A clone has a Juggernaut Hellfighter fixed mag kit, with evil features, and is a range toy, I'll run the Colt featureless with a brake and Sparrow Dynamics grip. The OEM 1 comes without furniture or sights. I'll use an early Colt Fiberite CAR-15 stock and 7 hole Colt CAR-15 smaller handguard I have thats on my 300 BLK build. I also have a Colt Cardinal Forge detachable carry handle, a Magpul BUIS, and a SIG Romeo 5 2MOA red dot to choose from for sights. Should be a nice piece of kit when. I am done.

Here is my 300 BLK build with that furniture and carry handle I will use on my new Pony.


Here's the lower I am getting: Notice it only says "Carbine" not Law Enforcement or M4.


This is like the Colt OEM1 upper I am getting:

LE prefixed serial numbers are banned in Commiefornia
CR prefixed M4 Carbines are OK, as long as it does not say Law Enforcement on the receiver. I went with a receiver that said just "Carbine" for an additional layer of security in case they decide to man M4 Carbines.....

OK, I thought you might be talking about some obscure BATF thing that made my Colt illegal here

No, it is just an issue this socialist wet dream that we call Commiefornia. They buy the votes of the great unemployed and illegal unwashed masses with government give a way programs paid for with my money they take from us that actually work for a living. An Illegal immigrant in Commiefornia gets free medical, food stamps, welfare, and free school.

Got the upper. Did a bit of a change and got a complete upper with M4 handguards and Magpul BUIS. I'll put my SIG Romeo 5 red dot (2 MOA) with Mo-tac automatic on-off.Only change is an AIM Sports A2 style Muzzle break. Looks the same as a standard A2 flash hider, but has a closed exit area making it a break.

The barrel extension is Colt, and the barrel is a Rosco, 16" M4, chrome lined 1/7 with Colt Cage Code.

The lower will be stock, with the exception of a Sparrow Dynamics featureless grip and a Strike Industries stock block.

Mated the CR6920 upper, that was shipped to me, with the CR6920 "Carbine" lower. Empty, with Magpul BUIS it weighed less than I expected at 6 pounds, 4 ounces.

Pictured it has the stock blocked with a Strike Industries stock block ($5), Sparrow Dynamics non-pistol grip, a Magpul 10/30 PMag, and an AIM Sports A2 Muzzle break. BTW, the safety on the 6920 is reversible! Works great for lefties, or if you have a fin-grip or Sparrow, you trigger finger flips it.





Same break on a different weapon:

Here is a set of the skinny Colt 7 hole 6320 handguards I am going to use. The heat shield is stainless steel, unless I am mistaken. Way too hard for aluminum.



Here's the early Colt Fiberlite stock I bought to put on the 6920. Has the N and 1 under the latch. Got lucky and got it for just over $100. They used them on the early 633s, M4s and Sporter II Lightweight Carbines



While I know they are not original to the 6920, but they are earlier Colt, so its still ALL COLT!

What is the difference? Any physical differences beyond the stamping or just what is and isn't on the list?
