I have a 1701P. It's really designed a lot more like a 10 meter gun. It's adjustable, but comes from the factory set at about 6 fpe. Haven't shot much in the past year, but if i remember correctly, has the same adjustments as a Marauder.
You need to purchase separate rear sights, doesn't come with any. It's heavy for a 10 meter gun, weighing about a pound more than the lighter guns.
Lothar Walther barrel, very accurate for short range. 50 plus shots on a fill, only comes in .177
Good trigger. I like the gun, but lost my indoor range to my wife's project so haven't shot much. Single shot, no option for a magazine. Might get it back out this fall when weather is sour and setup a 10 meter range in the garage.
