(5 out of 5) MMR 556/223 tactical rifle.
by Ed from Harrah, OK on January 8, 2025

I owned one and added a few things, scope, bipod, etc. Had a lot of fun shooting it. Unfortunately, an unexpected bill hit hard, and I had to sell it. ?? Heartbreaking. I sold it to someone I know, so it’s in good hands.

Things are getting better now, and I plan to buy another and start over. Yes, folks, it’s worth the money. Accurate. I did swap in a lighter trigger pull, just my preference. You can always add other accessories to the rail (light, handle, etc) and I had no problems with any of them. It’s easy to disassemble and clean.

Hope to buy another soon!
