Yea but they don't really do all that much, and a lot of them have downsides. In real life every attachment has a downside.

Alright son buckle up.
A scope, advantage: see further, disadvantage: less fov.

Silencer, Advantage: Less noise. Disadvanges: Less muzzle velocity and energy, Longer gun makes maneuvering harder, Gun has to be tuned to cycle using less pressure.

Flashlight A: lets you see in dark. D: Makes you visible.

Laser. (pretty useless since any good shooter aims down sights) A: lets you see where your barrel is pointed. D: Can alert enemy to your presence.

Grip A: Can improve handling and recoil. D: gets in the way, can snag on clothing/environment.

Magazine extensions/Magpul Loops/Magazine Doublers: A:Increase rounds in magazine,allows better manipulation of magazine, quickers reloads. D: More weight, snag on environment.

Bayonet: Increased melee range D: weight on the end of barrel.

You can't ignore weight because a heavier gun is harder to shoulder, and you can't aim as long. It's also make the gun harder/slower to handle. Weights of things like lasers, grips, and flashlights are negligible, but ammo is heavy, and weight near the barrel counts as a lot more.

It's not 100% but because there's a wide variety of attachments it's good enough for the casual observer. That's my excuse, and I'm sticking to it.

Good point it is suppressor, but silencer still works. I prefer calling it a silencer just because you also have flash suppressors. Which reminds me

Flash suppressor/Muzzle Breaks A: potentially less muzzle flash, potentially less felt recoil. D: Lengthens barrel, small weight on end of barrel.

Pretty much just a paper puncher. But I do have most of these attachments, other than a suppressor (due to legal issues) and bayonet.

My point is that most attachments have downsides.

M14 (M305) Which is a 14 lb heavy ass bastard. Ar15s are a hassle to own up here, due to them being treated as a handgun. Have a few other guns but nothing fancy. the M14 is the only thing with mounts.

Uh I'm not follwing

Ah. No ak sadly. I do have an 870 though. Other than that my other guns aren't well known. No handguns either, handguns are a pain in the ass in Canuckland.

That's how it works here, well you can own them for a collection, but you have to prove you collect them. Other then that you have to get an authorization to transport (ATT) whenever you want to take it somewhere. You can get an ATT that lets you take it to/from the range to your house anytime.
Where you from?
