Just Do It

Review by John R. on 27 May 2025 review stating Just Do It
Just as they say “Third Time Is a Charm” . The whole process in purchasing a firearm online through Rainer is effortless and now have a regular sales person I deal with. If you’ve waiting to see and you are someone that needs to read the reviews first, don’t wait just do it. No regrets at all with these guys.

Avg quality

Review by Les T. on 25 May 2025 review stating Avg quality
Although lightweight, I don't like the softness of the material. It's too flexible especially if I catch it at the wrong angle
