Hey gang i have a TM Sig 552 i have had since new ...i have had it for 7 years or so ...it has only seen around 3000 -5000 rounds and i have a few questions
1.i havent sprayed silicone into the barrel yet ..i have read that this needs to be done ?....true /false ...how is it done
2. is there any maintenance that i should be aware of (like the silicone thing)
3. it shoots around 285 fps what is needed and where can i get the parts and mods done to make it around 325 fps
