What is the difference between a bolt-action rifle and a semi-automatic rifle? Answers (1)

Proven Arms & Outfitters A bolt-action rifle requires the shooter to manually operate a bolt to load a round, eject the spent casing, and chamber the next round. In contrast, a semi-automatic rifle is designed to automatically eject the spent casing and chamber a new round with each pull of the trigger. Semi-automatic rifles offer faster follow-up shots, while bolt-action rifles are typically more accurate due to their design.

M18

Thanks to the guys at proven outfitters. They have great customer service and very attentive to details purchase my firearm over the phone because I needed a different SKU and they were so helpful and nice to deal with. This is my second m18 first one was the civilian version so I was not able to use the Romeo 17 so I purchased the one with it already.
