I wanted an update to my MR556 and saw this one from B&T. The price - I thought how could it be that cheap? I thought it was a blem but no - perfect.
Received it and installed it. Lockup to barrel nut and upper is tight. Perfect. The pin is not retained so a drop of blue loktite will ensure that it stays put. I wish it had a retained pin like the OG HK one but this is no big deal. However, after a range trip, I often take the piston apart to clean and lube.
Great product. Mloks are a great option. I guess it cuts about 6 to 7 oz off the front of the weapon.

Perfect
The 11" handguard is high quality and fits perfectly on my 16" Brownells A4 (HK416 clone) Am going to buy another longer version as I need more real-estate.
