The RRA LEGP can be fitted with a standard removable carry handle. It is an option that is for sale with the rifle.
The RRA quality is easily equal to Bushmaster, in fact the upper and lower fit a little tighter. The downside is the lack of a chrome lined bore and chamber. Fine for range use, but for a SHTF gun, I would prefer the insurance of chrome. Also, the Bushmaster uses tougher 4150 barrel steel, whereas the RRA uses 4140. Again, I own both and both are great rifles.www.sportsmansguide.com

, which is remanufactured. Very good quality, but might void warranty, but Georgia Arms will stand behind their product and repair the gun if needed.
I haven't tried the YComp, but the AK brake is very effective on the AR-15. Not really needed, but effective.
