During the Global War on Terror, a new type of weapon system was developed. The DMR is a magazine-fed rifle that is operated in the semi-automatic mode of fire by expert marksmen, or DMs. The 7. The DMR was also adopted to enable military marksmen to accurately deliver faster follow-up shots while engaging one or more targets on the battlefield.
It should be noted that the effective range of the DMR is dependent on several factors, including the skill of the operator, the quality of the optics involved, and the ammunition used.
The following are seven powerhouses that qualify as Designated Marksman Rifles. ArmaLite manufactures several carbine- and full-length 7. The MK20 upper receiver can accommodate folding iron sights, various in-line day and night sniper optics and devices, and other accessories as required. The SSR is available in Flat Dark Earth, utilizes and round magazines and can be easily operated with a suppressor.
HK The HK is a semi-auto or select-fire 7. The rifle features ambidextrous controls charging handle, safety and selectora retractable buttstock with spare battery compartment, an optional suppressor, and or round proprietary magazines.
The HK can also be easily configured to operate with a or inch barrel. The LA1 has a inch blackened stainless steel 5R Ultra match barrel, a proprietary monolithic rail, a detachable, adjustable front post sight, a detachable, adjustable rear sight or a carry handle, a two-stage match trigger, a proprietary LMT SOPMOD buttstock, plastic round PMAGs, a hardcoat anodized finish on all metal parts, and it is available in black or tan.
Other REPR models are also available.
Tens of thousands of M14s were refitted with optics, and in some cases new stocks and bipods, before being rushed into service during GWOT combat operations. The basic M14 has a fixed front post sight with protective wings, a rear sight that is adjustable for windage and elevation and a two-stage, 5- to 6. More accurized versions of the M14 utilize a two-stage National Match trigger that has a 4.
All M14 DMR variants are traditionally operated with a round metal box magazine and have proven to be accurate, reliable and effective under combat conditions. The Springfield Armory M1A1 rifle is an incredibly well-made semi-auto civilian version. It is currently available in different configurations. The Sage chassis is manufactured in lightweight aluminum and is equipped with a telescoping stock and an adjustable cheekpad along with a two-stage trigger and rail system that accommodates various optics and accessories.

DMRs are developed to fulfil this middle ground tactical role. DMRs, unlike the often bolt-action sniper riflesare almost always semi-automatic rifles as these have higher rates of fire than bolt-action rifles, and typically have larger magazine capacities 10, 20, or 30 rounds depending on the firearm and operational requirements to allow rapid engagement of multiple targets. These rifles have to be effective, in terms of hit rates and terminal ballisticsat ranges exceeding those of ordinary assault rifles and battle riflesbut do not require the extended-range performance of a dedicated sniper rifle.
DMRs often share some basic characteristics with sniper rifles when compared to the weapons carried by others in the DM's platoon. DMRs may have an attached telescopic sightquickly deployed stabilizing bipod to allow optimized accuracy and low-recoil in temporarily fixed situations or an adjustable stock. The designated marksman's rifle needs to function as part of squad and possibly at close quarters.
Most designated marksman rifles are based on an assault rifle that is currently issued by a nation's military, or on a battle rifle that was formerly issued. A battle rifle is a semi-automatic or full-automatic rifle that fires 7. These rifles were largely replaced by assault rifles firing the 5.
Conversely, some nations have also built rifles that were designed for the designated marksman from the ground up. Some designated marksman rifles will have some type of optical sight with a higher magnification level than the standard issue rifle. Commonly, the sighting system will be the only difference between the standard rifle and the designated marksman rifle, as is the case with the F88S DMR issued to the Australian Army.
Sniper rifles often have even greater magnification than designated marksman rifles outfitted with magnification, for example, the M SASS used by the United States Army, is equipped with a Leupold 3. In some cases, the designated marksman rifle will have a longer barrel than the standard issued rifle, however, this is not universally true.
7 Deadly DMRs
For example, until Octoberwhen the M4 carbine was approved as the new standard issue rifle, the M16A4 rifle was still standard issue throughout the United States Marine Corps. This no longer the case, however, as the M4 carbine has a barrel length of only mm Also, some rifles, such as the F88S Austeyrhave a barrel that is the same length as the standard service rifle.
The FD has an accurized barrel, also found on designated marksman rifles. Only the SVD and similar designated marksman rifles have a barrel of this length. In most cases, a designated marksman rifle will share the caliber and possibly even the ammunition type used by standard issue rifles. DM rifles may be issued with standard ball ammunition, or special match-grade loads, such as 7. Sniper rifles are almost exclusively deployed with match grade ammunition in order to take advantage of their full effective range and accuracy potential.
In the U. All designated marksman rifles in use today are semi-automaticsome are select fire. Sniper rifles are generally bolt action rifles, but can also be semi-automatic.

Talkgroups can exist for many purposes. You can have talkgroups for countries, states, counties, regions, cities, special interest groups etc. Just about any group of DMR users could have a talkgroup assigned to them if they wished to organize traffic that they can all monitor and take part in, without having to talk to each other one by one. So you need to make sure that you know what the various talkgroups are for each of the DMR networks that you may use.
Be sure to manage your Talkgroups separately if you use more that one DMR network! Keep in mind that talkgroups are created by network administrators and can be updated from time to time. Also, do not just create your own talkgroup without coordinating with individual network administrators. You can find an updated list of Brandmeister talkgroups by clicking the button below. You can search on this page and also export the talkgroups in various formats specific to your needs.
For example, if a statewide talkgroup is assigned to the local repeater on timeslot 1, anytime someone keys that talkgroup on the network, regardless of where they are, the audio will be retransmitted locally. In simple terms, this networks many repeaters together full-time for that particular talkgroup. What is a Dynamic Talkgroup? Dynamic talkgroups assignments are used for temporary activation on a timeslot on a particular repeater.
This type of talkgroup functions for a set amount of time AFTER a local repeater user activates it by transmitting on a repeater using that talkgroup in their radio. When the timer expires and no local user has keyed up again for a set amount of time… the timeslot and the talkgroup and release and the repeater is again open only to the talkgroups that remain static.
DMR Talkgroups Let's discuss talkgroups, what they are and how to use them. What Is A Talkgroup? Brandmeister Talkgroups You can find an updated list of Brandmeister talkgroups by clicking the button below. Frequently Asked Questions. What is a Static Talkgroup? A static talkgroup is one that is permanently activated on a particular timeslot by the repeater sysop.
This type of static assignment passes ALL traffic from the DMR network over the air on the timeslot it is assigned to. For example, if you are traveling in Colorado and wish to talk to a friend back home in Missouri, you could key up the Missouri talkgroup on a Colorado repeater that allows dynamic talkgroups and make a call on repeaters at home that have the Missouri talkgroup set as static. When you are done with your conversation, the dynamic timer will expire and the Colorado repeater will go back to normal.
All of the US Master server owners decided among themselves that they do not want any part in facilitating other amateur radio operators to knowingly or unknowingly break the rules that the FCC have made for us to abide by, these are the same rules that you sign to agree to after you successfully pass an amateur radio examination.
If requesting a Statewide talk group 4 digit please review the list below Talk Groupsif it shows as hosted by another network we will not be able to provide the state wide talk group s.
USA Server Admins will not provide these talk groups. TAC may be used for general conversation. Remember, these are Tactical talkgroups and NOT call channels! There should NOT be any nets on these talk groups.
If you want a net, please use and Re-Bridging any BrandMeister Talk groups to another network will result in your link being terminated. Talk Groups are only labeled for 3, 4 and 5 Digit IDs.
Due to the limited number of 5 Digit IDs available we are no longer labeling any new requests for 5 digit talk groups at this time. Although the 6 and 7 digit IDs will not be labeled they can be used immediately without Master Admin Approval. It seems people like to experiment and this is NOT the place to do it. We are a guest to those talk groups. TAC - are bridged between different networks through DMRX so that communications between different networks are possible. Please allow time between each transmission to allow others to also use the talk groups.
When a users on a cbridge activates a talkgroup, they will not hear anything until the next transmission starts. We are a guest on these talk groups. USA Nationwide should be used for that. If you wish to have longer conversation, that is what the TACs are for.
Not to initiate a conversation. The TACs were being used as call groups, which they aren't. We have also removed the auto-static option on the hotspots.
This means they will time out after a duration of time. State talk groups should be used as call channels or short conversations of 15 minutes or less. Some states have chat or tac talk groups of their own that you may used for longer discussions. Many repeaters carry their local statewide talk groups as static talk groups. Please be courteous and remember how many repeaters you may be keying up when using a statewide talk group.
If you are using another statewide talk group and are not in communications with someone else in that state, please be courteous and move to a different talk group. A complete listing of all talkgroups can be found by clicking here.
We also support those wanting to connect talkgroups from their existing c-Bridge. There are four BrandMeister servers, which are geographically dispersed, located in the US. For the best performance, please select the server that is closest to your repeaters physical location, or gives the lowest ping times to your location.
