Ok so I am looking for advice, I want a good dmr and one of my friends recommended a spring rifle for a dmr. Can you guys tell me what you think on this and if any give some recommendations? Looking for an m4/m16 model or something of that family. Maybe m14 or something like an acr. Preferably something upgradable. Price range is around $100 as of now but maybe getting some $ later in the month.
