1. 4 mag mag pouch? Likes, dislikes. Ordered 2. Compensator, worth it? Will I need to slide back the front sight and re-sight? Or just get a flash supressor from somewhere else? 3. Will the buttstock mag holders work with the ProMag 15 rounders? I ordered the 2 mag deal. I guess it comes with 2 brackets? I ordered the side rails. I will look for a flashlight. I have yet to try mounting the laser from my JHP45 on there. I did order a black hat! I deleted ordering a camo one. Next time!
