Getting closer, this is our current design. Exterior dimensions are the same as our other fake cans -- just under 1.25 x 5.5" and it covers 4.5" of barrel length.
As designed, it would fit the following barrels/gas lengths, assuming a 1" long gas block (i.e. not an FSB):
- 10.5" or longer barrels with a Pistol gas system,
- 14.5" or longer barrels with a Carbine gas system,
- 16" or longer barrels with a Midlength gas system, and
- 18.5" or longer barrels with a Rifle gas system.
Even with hollowing out the inside, we're looking at about 340 grams (just under 12 oz) ... does that put anybody off?
I hope to have a finalized design and an ETA within a week or so.
