Funny how people bash RRA! I have two Colts, a Bushmaster, a RRA, a SIG M400. The RRA is a great shooting rifle and reliable as any of the others! I do have a BCM bolt carrier group in it!
How anyone going to tell me that the RRA is much different from any other M4 variant? Or the Bushmaster lower i have with a Colt upper? All the lowers are essentially the same with different logos embossed.
If you like the RRA rifle, go for it. They are an all around good rifle in use by many Law ENforcement agencies. Proven rifles!
Just know you will not fit in with the M4Carbine Forum types who are all haters outside thier world of custom built rifles that are no better than any factory rifle!!!!
May God make smooth the path you follow!
