Vism ar15 m-lok handguard - VISM AR15 M-LOK Carbine Handguard

I bought this hand guard as a replacement for the plastic short hand guards that my S&W M&P15 came with. My AR15 was the “ready for optic” configuration meaning there was no metal front sight or rear sight. As this is my first time buying this product, I wasn’t sure it would line up perfectly with the gas block on my rifle. As I took off the plastic hand guards, the VISM hand guard lined up perfectly based on my estimation. As I pushed in the bottom piece of the new hand guard, no problems or issues. Installing the top piece, it slid in perfectly but I needed to wiggle slightly where the delta ring and it all came together perfectly. I had no issues screwing in the 6 hex screws it came with. Should I have another rifle type like the M&P15 sport 2, I wouldn’t hesitate ordering it again as it’s light, it makes my barrel free-floating and it’s very long for any additional accessories I might want to add. Good thing it’s all M-LOK and came with some additional rails pre-installed. Happy with the purchase and would order again if needed.
