I owned a S&W and sold it to buy a Noveske. The Smith was a very good rifle, never had a problem with it, but I sold because I wanted the best possible rifle, my "one gun" I could trust implicitly.
Research the TDP that defines how military M4s are built. Some elements of the TDP, such as barrel steel composition, chamber dimensions, inspection of the bolt, staking of gas keys, and more, directly affect reliability. Colt is objectively better than RRA on the points I mentioned above. Some people are willing to roll the dice to save a couple hundred bucks. I think that's a stupid state of mind for a "bump in the night" gun.
You want this rifle for self defense? Then spend the extra and buy the Colt. You'll never wonder "what if." If you have the coin, there's literally no reason to buy less than top-tier quality.
