Here's the scoop; I just this minute verified the prices on Delta's [url]www.deltaforce.com[/url] and Smith Enterprises' [url]www.smithenterprise.com[/url] sites.
Prices are Delta/Smith
M1 Garand: $60/$100
M-1 Carbine: $40/NA
Shipping is about even.
The Garand unit replaces the gas cylinder lock and uses your existing gas cyl. lock screw as usual.
Note that Smith, the original manufacturer, no longer lists units for the M-1 Carbine.
Also note that I have NO financial interest in any of these outfits.
