H&K MSG-90 Sniper Rifle Germany Battle Rifle

Based on user experience (particularly US Marine Corps scout-snipers and FAST teams,  and the German GSG-9 and KSK), Heckler & Koch made some improvements to the H&K MSG-90 Sniper Rifle,  producing the MSG-90A1 Sniper Rifle.  It is somewhat heavier, but  has a number of new changes to the bipod, stock, and the barrel.  The barrel now sports a full muzzle brake; this brake can be removed to reveal threads for a suppressor.  The iron sights have been put  back on the weapon to allow for emergencies,  and these iron sights are micrometer-adjustable.  The H&K MSG-90A1 Sniper Rifle can use the 50-round drum of the G-8 battle rifle (though reportedly few units ever actually use this capability).  At the rear of the ejection port,  a small brass deflector has been added, to correct a small problem with case ejection (sometimes hot  cases would end up going down the shirts of shooters of the MSG-90).  In USMC service, this weapon is known as the MSG-90-DMR (Designated Marksman Rifle).

In the mid-1980s,  Heckler & Koch began development of an upgraded PSG-1.  Originally, the new rifle was to be called the PSG-3, but  the name was later changed to the MSG-90.  The MSG-90 is basically a PSG-1 built using the latest  materials and construction techniques, such as a cold-forged tempered barrel, a reduced (but fixed) trigger pull, a smaller padded stock that is adjustable for length and the height of the cheekpiece, and a MIL-STD-1913 rail able to take virtually any sort of optic or accessory.  The trigger is also wider for a better grip for the trigger finger.

A standard bipod replaces the tripod of the PSG-1, but this bipod is attached to an internal T-rail, allowing it to be easily detached and replaced with a sling swivel or some other accessory.  A (rather long) flash suppressor is fitted to the end of the barrel.  The firing selector was made ambidextrous.  The MSG-90 has no iron sights; the standard sight for the weapon is the same 10x42 Hensoldt sight fitted to late-model PSG-1s.
