This is a new 12 gauge upper conversion for the AR-10 system form Intrepid, of Salt Lake City, UT. www.intrepidts.com
Although it is referred to as a 12 gauge, it is NOT the same rimmed 12 ga shell that we are all familiar with. It uses a new proprietary 12 gauge diameter round that has a rebated rimless round. The case is molded entirely from plastic. This allows for trouble free feeding, no worries of a rim hanging up on the rim of the shell below. (Lee-Enfield users will understand this.) It also eliminates needing a very curved magazine to accommodate all those rims.
I specifically asked about having a gun with no ammo if the company was to fold, or the project was dropped. The spokesman said that they are in talks right now with a major US ammo maker to produce this new cartridge for Intrepid. Interestingly, it was the (unnamed) ammo maker that first approached Intrepid, not the other way around.
The new round is carried in an 8 round mag (8+1 in the tube) that perfectly fits a SR-25 standard magwell. As well as the 8 rounder, there is a 3+1 for big game hunting, and a 2+1 for waterfowl hunting. They are also planning on releasing a rifled slug barrel and a choke barrel soon.
A .410 and a 20 ga version is planned for the AR-15 lower within a year.
I realise that as long as the AR series remains RESTRICTED in Canada, this greatly limits its usefulness and desirability here. But it is nice to keep aware of what is out there.
No word on a Canadian importer yet.
Retail expected to be ~$1900 US.
