Here are my 3,
Top is a full on Mike Cripps build, based on his recommendations and a TM 5.1. snappy, shoots very accurately, 340fps on Black, Virtually all internals are custom as is Slide. This is my Plinking gun
Middle is a medium Mike build, again based on a TM 5.1. Barrel, Hop, Nozzle upgraded. 80% of the above for half its price. 330fps on Black gas, Slide is original TM. Notice the MantisX unit , this is my dry fire training gun
Bottom is 2 year old Novritsch SSP1 with cutaway slide and short stroke kit, all else is standard. Main Skirmish Side arm, its survived, rain, mud and everything its been asked of. Reasonably accurate, loud, effective, reliable. 340fps on Black Gas and works well in the cold
