Last night I ordered a PSA Glock 9mm lower and a 7.5" upper. Today I picked up a Vortex Sparc AR and am planning on getting a KAK Shockwave brace to mount on a Phase 5 tube I already have. Any feedback or tips would be appreciated. I figure I'll mostly run 115 grain ball rounds through it. Frankly, I got it more for a range toy than anything else as my range allows AR's but not rifle calibers in pistol format due to noise. I'll post more when it arrives.
