The Spyder MR1 is a MilSim paintball marker designed and manufactured by Kingman Group, now superseded by the Spyder MR2 and MR3 models. Design The Spyder MR1 is a mechanical marker. Much like its newer, electronic counterparts, the Spyder MR2, MR3 and E-MR1, it has an offset feedneck for rifle-like sighting, a 12 inch muzzle brake barrel, an anti-double feed detent to prevent double feeding. Being a mechanical paintball marker, it features only semi-automatic rates of fire. It also has a two finger trigger (or double trigger) for faster firing and less fatigue. It has two stock colors, matte black or matte olive and retails with a detachable stock. E-MR1 E-MR1s are the electronic counterparts of the MR1s. They are upgraded with: Electronic grips(E-grip), capable of firing 15 in 3 modes of operation: semi-automatic, full-automatic, and bursts 2-way adjustable triggers, adjustable to players's preferences Delrin bolts Removable adjustable shoulder stocks E-MR1s are available in matte silver or matte olive. MR1 Sniper The MR1 sniper is a long range counterpart of the MR1. The MR1 sniper is rated higher than the original marker for its superior accuracy to countless other markers. The MR1 sniper features a 16" barrel rather than a 12" on a standard model.
