Anyone have any experience with this gun? Does the porting help?

[Robert inOregon]

Help what? Diminish your hearing. Increase pyrotechnic effects. Looks.

Yes, it does all the above and more. It actually reduces recoil in the little flame thrower. ;)

Love mine, and yes it does help with recoil.

For the last week I've takem my 2.5" M66 and my 3" M66 F-Comp to the range and shot 125 gr. .357 Magnum ammo DA from a standing modified Weaver position both stay within a 6" target at 25 yards 90%+ of the time. They are both 100% reliable with great triggers (after trigger jobs) and all the combat accuracy a person can ask for. In addition they are a joy to shoot. Of the two I do favor the F-Comp, but they are both great! Dennis
