If we drift back to the OP's original question - What is the most value-priced "M4 style" rifle available at retail in Canada that is NOT of Chinese origin?
Probably it will be the NEA M4-gery for under $1000 when it eventually gets to retail, but for now - what is the value king?
If we're talking guns we have (in stock), but can't sell commercially, the Stag Arms G2 LE 14.5" is the closest to Colt USA 6921 than any other gun in Canada that is not a Colt 6921. The difference between the two would be that Colt drifts the taper pin from the left, and Stag drifts the taper pin in from the right. LE sale only at the moment, unfortunately.
Colt M4A1
Stag Arms G2 Semi-Auto
The Special Production for AEI 10.3" Stag G1 Mk18 Profile, are also the closest to the M4LE Mk18 guns sold in Canada. Also available for LE.
Special Production Colt M4LE Mk 18 Semi-Auto
Special Production Stag Arms G1 MK18 Semi-Auto
The standard production Stag Arms G1 is the mirror of the Colt Commando 11.5".
If we're talking guns we have in stock and CAN sell, the Stag Arms G3 LE, 16". A 4150 1/7 CMV M4 Profile bbl, tastefully customized for Canadian export. Sold as the Model 1 & 2 Govt Editions. We ship it with a Phantom Compensator, which is a upgrade to a standard A2 flash hider.
Colt 6920 LE Carbine
Stag Arms 1R LE Carbine
To keep going, Colt doesn't offer a 20 LE gun at the moment, but it does have the R0901 M16A4 in the Defense Line.
Stag Arms Model G4 LE AKA 4R Govt Edition.
I am familiar with Colt LE lineup, and am familiar with CMT/Stag Arms LE lineup, I have seen the other likely candidates. Assuming the 1/7 barrel, in material and fabrication and configuration the Colt LE and Stag LE guns are indistinguishable, but I still think Stags are 'prettier'. If you really want to split hairs, the 'big pin' FCG pins on many of the Colt LE kinda disqualify it from being 'as close'.
Stag/CMT cut parts are authorized in US DOD M4 production.
It's not a stretch of an answer to say that Stag's lineup most mirrors Colts. Particularly for international markets.
