Everything fit as should trigger ok little creep decent reset. Missing trigger guard reason for 4 stars

Nice kit


Just got this kit for Christmas and all the parts seem to be great quality for the price. Not sure if it was just an oversight with the kit I got or if the pic isn’t accurate but my kit did not come with a trigger guard as shown in the pic. No big deal but thought it worth mentioning. Otherwise, I’m very pleased with the quality and excited to get it assembled.
