AMP DSR No. 1 .338 Lapua Mag

Marine snipers working in Iraq and Afghanistan know all about…


Marine snipers working in Iraq and Afghanistan know all about the benefits of smaller rifles. The latest sniper rifle design to be put forward by the leathernecks is a 16-inch-barreled .338 Lapua Mag. The thinking is that by lopping off 10 inches of barrel, the rifle can be shortened to fit inside a pack so that a sniper can deploy with an M4, like a regular grunt, and not attract undue attention with a long, scoped weapon, marking him as a sniper. There is, however, a more sophisticated solution to miniaturizing a sniper rifle.

amp2.gifBullpup rifles incorporate the rifle’s action behind the trigger, allowing for a compact overall length without shortening the barrel. Bullpups are not new; they date back to World War I, but they’ve never been very popular outside of Europe, where the best examples originated. The Steyr AUG might be the most widely known bullpup. The British army began issuing a bullpup in 1985, the SA80; FN’s P90 is a more recent example.

The great advantage of a bullpup is that it allows you to scale down the overall length of a rifle without giving up downrange ballistic performance by shortening the barrel. The disadvantage is that by placing the action behind the trigger, usually about where the shooter takes his cheek weld, ejection of spent cases prevents the rifle from being used by left-handers. There are some bottom-ejecting designs, but by and large bullpups are right-handed only.

Recognizing the need for a short overall length sniper rifle, yet not wanting to give up any ballistic performance by cutting the barrel, a German company named AMP Technical Services has produced a bullpup sniper rifle of exotic design.

Gun Details
Designated the DSR No. 1 (for Defensive Sniper Rifle), the rifle comes with a 25.6-inch barrel yet stretches the tape only 39.4 inches overall. Compare this to the current issue FBI sniper rifle, a .308 with a 24-inch barrel measuring 45 inches overall.

The DSR is to a sniper rifle what a dragster is to a family sedan. Like a dragster, the gun is built on a long rail with the action, barrel, sighting plane and stock all part of the aluminum and titanium rail. The entire rifle is modular and can be disassembled virtually down to the ground without tools.

The bolt is a six-lug, front locking design with a nice, short throw of what appears to be about 40 degrees. The bolt handle is positioned just behind the locking lugs, giving the shooter maximum leverage and greater control over the bolt throw for faster follow up shots.

The receiver is made of a high-strength aluminum alloy. The locking recesses for the bolt are in the barrel, obviously, and not in the front of the receiver. The match-grade barrel is made by Lothar Walther.

trigger.gifThe action is fed by a detachable box magazine holding either four or five rounds depending on caliber choice. The DSR No. 1 is available in .308, .300 Win Mag and .338 Lapua Mag. There is a spare magazine receptacle in the rifle’s rail mainframe, forward of the trigger.

The trigger is a two-stage design with a definite “catch” at the second stage. The safety is a three-stage type with the full-safe position locking the bolt, half-safe locking the sear but releasing the bolt and, of course, the fire position.

“Stock” is not the right word to describe the rear portion of this rifle. Call it a “shooter interface” but whatever it is, it’s the epitome of ergonomic design. The heel is adjustable for length of pull as well as angle. The cheek piece rises up or down to position the shooter’s head comfortably in line with his choice of optic.

The DSR has a vertical riser inside the rifle’s mainframe just forward of the heel. Inside is a spring-loaded monopod for adjusting elevation. The shooter grips the monopod tube housing using the proper two-handed hold on a benched rifle with the support hand tucked back, and can instantly deploy the monopod by pressing a deeply knurled release knob.

Extended to touch the ground by spring tension, the monopod can then be fine-tune adjusted by turning the release knob with the support hand, all the while maintaining a proper rear support grip on the monopod housing. The monopod has a second leg inside itself, a telescoping design, which can be extended for extreme downward angle targets. I’ve never shot, let alone seen, anything as well designed on any precision rifle.

The rifle’s grip is a target-style pistol grip with a heel support, finger grooves and a palm swell for right-handed shooters.

The rifle incorporates an unusual bipod mounted on top of the rifle’s mainframe rail. A complete reversal of the usual bipod, the entire rifle hangs from the bipod instead of being supported by it. There is a wide range of cant and traverse built into the bipod. The legs telescope, spring loaded, to extend as needed. When not in use, the legs pivot back and lock into recesses on the mainframe.

optic.gifShooting Impressions
Our test rifle was chambered in .338 Lapua Mag, the monstrous long-range cartridge built on the cavernous .416 Rigby case. Its ballistics are a 250-grain FMJ at 3000 feet per second (fps), making it a true 1000-meter round with a high ballistic coefficient to make it over a half mile without suffering too badly from wind drift.

Thanks to the dual-port, titanium muzzle brake on the DSR No. 1, shooting the big cartridge felt like nothing. Our test rifle, complete with a Leupold Mark IV scope and an Aimpoint in a custom SureFire scope mount, weighed about 19 pounds, so recoil was totally mitigated.

With a 200-yard zero, I was able to ring a 500-meter gong by holding at the top of the plate. Using the rear monopod’s adjustment wheel, I could traverse a row of plates from 200, 300, 400 and 500 with ease. While the recoil was negligible, the muzzle blast was pronounced. I would not want to be next to the gun with that muzzle brake.

Working the bolt was awkward, but like anything else, if you practice with it, I’m sure it will feel natural after a few thousands reps. Repetition is the mother of all skill, as an instructor used to say.

The factory claims that the DSR No. 1 produces accuracy of 0.2-MOA, or 2 inches at 1000 yards. The best we could do between three shooters was a 6-inch group at the grand mark. Needless to say, wind and mirage play a big role in long-range shooting.

Final Notes
For an exotic design, the DSR is the most radical rifle available. It makes the Blaser 93 Tactical look pedestrian in comparison. The DSR No. 1 was developed for Germany’s GSG-9, the elite anti-terrorist police unit. It is every bit the ultimate bullpup.

    The DTS SRS is a very nice rifle, but a DSR it is not. I need a 50x and a machine rest to find out what this rifle can really do. I have a few friends with SRSs. They all really want the DSR.

    Watch a re-zeroing after changing the scope one notch on the picatinny rail.

    There is a company here in the u.s.a. (desert tactical arms) that has ripped of the dsr-1 design claming that thier the one who redesigned the sniper rifle and was the first to design a bullpump sniper rifle (they call theirs SRS 338)the only thing they did was leave off the the front mag holder and redesighn the stock and leave off the bipod but everything else is the same down to the quick change barrle and it comes in 308. 338 lapua and 300win mag its been on the discocery channel modern weapons and in a few differente magazines and just noticed their advertised on this web site also

    $23,000 here in Australia with a S&B 5-25×56 and DSR mounts…and worth every cent.

    Best 5 shot group to date (prone using bipod) is 89mm h x 49.5mm w at 900m. Three of those were about 10mm centre to centre.

    3.5″ x 1.95″ @ 984 yds
    .24 MOA x .15 MOA

    Shooting from a bench in ideal conditions? God knows.

    Master the wind (ha! ha!) and this baby is good for 2000m.

  • can someone tell me how to justify $15,000.00 for an “aluminum” receiver? I think for the price, it should be Gold-plated Titanium? 😉

    maybe someone can tell me more about the aluminum they use? Is the barrel cryogenically treated to minimize differences in shot placements from cold bore to hot? What bore lining is used, for $15,000.00 hard chrome is just not good enough. Are the internals and externals coated with NiB-X or at least TiN or TiAlN with Cerakote Gen II? or do they use cheap parkerization or ionization processes?

      You don´t really know what you are talking about, do you?

  • ertsu

    Lol lapua is finnish…

  • Try contacting Global Rifle in the UK
    They can source you a DSR


    You’ll notice the AMP logo on the left side of the receiver, followed by the DSR 1 logo.

  • Pingback: what is this? -()


    If you want a DSR 1 you should contact the factory
    and send a e-mail to Mr Ingolf REUTER
    He will sell you the rifle, conversion kit, scope and scope mounts.
    Ingolf informed me that they do not cooperate with AMP.TS anymore, and they do not supply any items to AMP.TS.


    I own a DSR 1 rifle, and I’m interested to have informations on the scope mount shown on the picture of your DSR 1. May you, please, inform me about the website of the company who sell it ?

    Thanks a lot

  • BaBaBlack

    Hey, I’ve got one in 300. I bought from CQB…. Anyone know how many are here in the U.S.? I seem to remember CQB telling me something like 12 but not sure.

  • Frank

    August 2008 can i get a copy

  • Jesus

    I have DSRs in .308 and .338 😉 I bought them long ago from the now-defunct “CQB Products” in California. It took 18 months to get them. It was like pulling teeth.
    Your best bet is here – these guys have reliably provided spare mags for me, and I have something else on order with them that is slightly more expensive than a magazine 😉
    If they will sell you a rifle, be prepared to do some import paperwork. This place is the easiest:
    it will cost a couple hundred bucks to do the paperwork.
    It is possible to get one of these, it will cost a lot of money and you may pull your hair out waiting, but good things come to those who wait! And who have an arm and a leg to sell for one of these puppies.

    You can buy back issues through this site. On the right hand side, it says “ON SALE NOW”- they’ll send you one if you order it- It should be at Barnes & Noble or Walmart.

  • howard aldendorff

    it is sept and I can not find on newsstan. how can I buy this article , or monthe, from publisher?

  • Andrew

    This price for one of these is around $15,000 but I have yet to find a dealer in the U.S. that has them listed on their website.

  • Jason

    I contacted the manufacture here is what he said

    “We do not have a distributor in the U.S.
    We do not authorize anybody to take or bring the DSR 1 to USA, because of the USA liability laws.

    If it is done it is totally on your own risk.

    Canadians may contact:

    The Shooting Edge
    Canada ”

    I have yet to find the price for this beauty and how I can obtain one… But I will find a way. If anyone knows of a way please pass it on.

  • Aaron

    Dusty, So the DSR is an awsome rifle but how much does this bod boy go for fully equipted? I wish I could aquire one here in the US, but it sounds like there’s no way possible huh?

  • Simon


    I’m trying to find pics with uk soldiers or sas using this beautiful sniper rifle.

    Could you please help me??
    Thank you

  • Dusty

    I have a AMP DSR-1 I got through an SAS contact and imported from UK in .300 WM. Fuckin accurate. Beats my other heavy BR rifles. Puts three shots into same hole at 300m no sweat!

  • Cameron Hopkins

    The last importer of AMP’s DSR is no longer in business and the German manufacturer does not currently have a U.S. importer. There’s no reason that the gun shouldn’t be available here other than perhaps it’s so expensive and exotic that no one wants to invest the capital necessary to start an importing business. You can try asking the manufacturer directly, but I haven’t had much luck with responses from them (maybe the language barrier):

    Thanks for reading

  • vtula

    Why isn’t it offered in the US?
