I remember those.
They're non-functional, but have to be otherwise, like working guns.
They had blue furniture on them to designate they were not "working" guns. And blue was also representative of the air force colors too because they had the contract for them.
I remember a photo of a few hundred of them on a pallet of the factory floor before they were shipped out.
I'll see if I can dig it up for you.
Here is what my buddy Tom (sales manager for Olympic) said about them in a post at oa2.org
---------------------------------
"
The AF contract is for 5,000 plus units of the Cobalt Trainer® rifle. These rifles are exclusively available through Olympic Arms and utilize a patented lower receiver, approved by ATF as a non-gun.
These rifles are filling a gigantic need in the military, LE and security businesses for training personnel without having to put a real (capable of killing your fellow trainee or instructor) rifle into the hands of the trainee, AND (perhaps just as significantly) without having to take a functional rifle out of the field.
The Cobalt Trainer® functions in every way as a standard AR15/M16 variant. The AF contract calls for M16A2 variants. The weapon can be charged, it has a moving trigger, a fully functional, but dimensionally different bolt carrier assembly, an unrifled barrel bore, fully adjustable sights etc. Everything that a trainee would need for total weapons familiarization and training short of BRM.
It looks the same as an M16A2, fells the same, handles the same, breaks down the same, cleans the same, disassembles and reassembles the same etc. You can lock in a mag, and drop it out utilizing an unmodifed mag-catch system as well. It just does not, and will not ever be capable of real firing.
They have already been sold to the AF, Army, and LE and security training agencies world wide and has become quite a market for Oly. A similar rifle is being manufactured for, and sold by Laser Shot® for their simulator training systems as well.
But the reality of the market is, if it were not for these 5,000 units, it would be 5,000 units of something else. Demand for anything AR15/M16 related, and especially Olympic Arms product is very, very high.
