I've been buying from CDNN for at least 20 years, I assure you it's not a scam. Have purchased firearms, magazines, gun parts and I'm sure other "stuff". Never have had an issue with them. They're legit.
Same here, crappy weather keeping me from going out again.
Yes fired it stock. Worked fine, dialed in the irons at 50 yards.
First off I noticed something about the B5 grip was aggravating my middle finger but oh well ya continue. After a while it was really getting raw so I began to look at...
1:8 will be good from 55-77gr. Just gotta get out there and see what your barrel likes the best. Each barrel has its preferences, you gotta find out which.
And this ^ is concerning best accuracy. For bulk purchases for range or stocking up any respectable brand of 193 or 855 will do.
Pistol: Even though it was publicly announced a few days before SHOT - Glock 47.
Rifle: IWI Carmel
Shotgun: Beretta A300 Patrol
Honorable mention: Beretta 80X
Hmm didn't figure a civilian model designation would effect a military model designation. The Colt M5 is a 5.56mm and the SIG is 6.8mm, two different carbines.
