Finished my DMR today! I was waiting on a the PTS grip because they're awesome.
Here's the information regarding DMR limits and such from SAASMaine:
- The DMR must be semi-locked. This means that the rifle is physically unable to fire in full auto.
- Binary triggers on DMRs are expressly NOT allowed.
- Joules limit: 2.26j
- Medium Engagement Distance (MED): 75’. Because of the MED, the designated marksman is required to carry a secondary that shoots at or under the 1.86j field limit.
- The only replicas allowed to be DMRs are ones whose real steel counterpart fires 7.62 NATO (or greater).
- They must be equipped with a magnifier optic.
The DMR is based on semi-automatic realsteel rifles used in combat for longer, more accurate shots, but without the slower reload time of a bolt action.
Requirements for DMRs:
In airsoft, the designated marksman is a support and suppression role, much like a SAW gunner, but instead of accuracy through volume, the designated marksman relies on accurate long-range shots. The difference between the designated marksman and sniper is that the designated marksman stays with their squad, while snipers tend to operate in a team of two (spotter and sniper), or as usual in airsoft, a team of one.
Designated marksmen should have accurate longer-range and more powerful rifles than a standard rifleman. These are referred to as a Designated Marksman Rifle, or DMR, and are not widely used in Maine.
DMRs are a time-consuming and EXPENSIVE upgrade. Stock components are typically not beefy enough to withstand the awesome strain put on them from the stronger spring, which is an M140 or bigger. This means a high torque motor in concert with specialized gears. It means having a radiused gearbox. It means a better barrel. It means a better bucking. It means using heavier, and more expensive, BBs.
Thanks!
