Cheap B5 Grip Review by Derrick
The B5 grip is just okay. I bought a Magpul MOE to replace it and my shot groups improved. I polished the trigger sear and put the JP 3lbs, trigger springs in with the original build. (Posted on 9/10/2017)
Good set was missing two pieces Review by Kevin
Overall everything seems like solid quality, unfortunately I got a trigger guard and no hardware to install it. Other than that everything fit together smoothly. (Posted on 7/5/2017)
