It's based on barrel threading and caliber. AKs have left hand twist muzzle threads, M4s right hand twist. The threading is also different dimensions, 14x1.0 (14mm diameter, 1mm between threads) vs 1/2-28 (1/2" diameter, 28 threads per inch). So thread-on suppressors sometimes aren't interchangeable because of how the barrel threading, or lack of threading. Caliber-wise, a 5.56 suppressor can be used on a 5.45 barrel, as seen in game with the 101 and 74 sharing a suppressor. But shooting a 7.62mm round through a slightly bigger than 5.56mm hole isn't a good idea for obvious reasons. However, that being said, at least the NATO suppressor isn't a screw on variety that replaces the flash hider. It's actually a quick-detach suppressor that looks to be an AAC M4-2000. Regarding realism, it wouldn't work with the current M4 nor AUG flash hider depicted in the game. The AKM in the game had the traditional muzzle brake in that it's just a bare muzzle with a slanted cut. There's basically no way to mount a suppressor without at least armorer-level modifications as there's no threading and no muzzle device to securely attach a suppressor to.

DaveAzoicer +1 He came to my location and he basically handed over a tent with goodies that we found while trading!

Yeah me too, how do you want to trade? But I'm only available for an hour or so.

I can be on in 2.5 hours or so. I'd take an SVD (and a couple mags) as well if you have an extra. I have lots to trade, let me know what you need.

Any tank traps, barbed wire, or bear traps?

What? I don't get it. There's a book called Ready Player One about an Easter Egg in a mmorpg that's worth like $200 billion and how the winner discovered it something like 5 years after the contest started. Great book if you're a geek.

Also a way of detaining someone or slinging their weapon, not just lowering it. There are times I'd help someone, but he has a long gun. I don't want to get shot in the back, so I'll generally kill him on sight for safety and ask questions later.

Reduce inventory space or separate it like secondary ammo and bandages, make food less of a constant need. That way having an ally allows the group to be better off than killing a dude and taking his beans. Also make all logging off have a long wait period and crashing or alt f4 causes your body to persist in game for a minute. A major tool of bandits is ghosting and combat logging to avoid both zombies and players. I think an alert if a player logs in within 30m would be a good thing, it doesn't tell you where they logged in, only that they are about to appear.

The 249 is a great hero/survival weapon. Ammo density is unmatched (so you can hold more supplies) and you can use stanag sd mags for quiet zombie kills.

How many members do you have?

We talking about reality or in-game? In-game, the main differences are 5.56x45 vs 7.62x51 and all that entails... 7.62 does more damage and shoots flatter, but has more recoil, more noise, and less rounds per magazine. In reality, completely different operating system and weapons. The DMR is an accurized M14. The Mk12 is an accurized AR-15. Differences between a M16A4 with ACOG and a Mk12 in real life are pretty big. The Mk12 has an 18" stainless steel match barrel that's free floated from the hand guard. The M16A4 has a 20" chrome lined 4150 steel barrel that is not free floated from the hand guard. The Mk12 generally utilizes a collapsible stock, the M16 has the standard A2 stock. The Mk12 uses a M16A1 or M4A1 lower receiver for full auto and also has a 2-stage match trigger. The M16A4 has burst fire, which is worse for accuracy in terms of consistent trigger pull, and has a much heavier single stage trigger. The Mk12 has flip up sights with a variable 3-9x or 2.5-10x power scope, The M16A4 has a fixed front sight and a fixed 4x ACOG. Scopes are generally dialed in for bullet drop and sometimes wind, but the ACOG is designed be zeroed and left alone, using only hold-overs. The Mk12 has a bipod. The M16A4 can have a bipod, but using it on the non-free floated hand guard can change the zero over longer ranges. The Mk12 has a suppressor mount on the muzzle that doubles as a muzzle brake to reduce felt recoil. The M16A4 has an A2 flashhider that doesn't mount most suppressors and doesn't do anything about recoil. So basically the only parts the Mk12 and M16A4 actually have in common are, off the top of my head, the lower receiver itself (although it's cosmetically marked differently), pistol grip, trigger guard, bolt catch, magazine release, safety selector, charging handle, the bolt carrier group, gas tube, and some small springs and detents. I believe the upper receiver in the Mk12 uses an M4 upper rather than a M16 upper, which has different feed ramp cutouts (namely, the M4 upper receiver has them and the M16 upper receiver does not). In-game... the main differences between the M16A4 ACOG and Mk12 will be the optic.

I'm looking for a M16 ACOG... Can trade a m4 cco sd for one. Found one last night.
