LaRue FUG
KAC
Quoted:
Many people use them. Integrated weapons lights/ lasers make sense, but I've never used one ever. Is it something based on personal preference or is it strongly recommended.
I prefer to use them only on my carbines, they're quicker to aim at multiple targets, makes the weapon stable when firing, and less strain on the hand when carrying my carbine for long periods of time.
On my 20" rifle I don't like to use them because I usually pass my targets when aiming and always have to go back to correct my aim.
The first time I used a VFG was on my then new Steyr AUG A1 carbine way back in 1989
I quickly found out back then that it was very easy and fast to aim at different targets, I remember I had a lot of fun shooting plastic gallon containers even sometimes hitting them in midair.
Try it for yourself if you have a buddy that have one or just buy a good quality VFG (or a cheap one if you desire), if you don't like it just sell it, you won't loose much money with quality brands.
