BRN-180s Handguard Adapter

Bought this product to make a BRN180 10.3 into a VAL. The adapter can fit without removal of the gas block with some light filing of the inside of where the guide rods rest. And some additional profiling on the inside on the front of the adapter where it has an unnecessary excess of material interacting with the barrel. There is a lot of mounting material that is a little excessive for its use (it’s a floating barrel after all). I wish the thread pitch was included in product info (#8-32). Only other idea would be to add additional methods of handguard mounting other than the AERO systems.

At time of purchase, the website listed two different parts depending on the upper being 300BO or not, with the *Required* selection of one or the other. As such, I ordered one of each for flexibility. What arrived is two of a single part number with a hand-written note on the invoice that says a manufacturing change means its no longer two different parts. THEN UPDATE THE WEBSITE TO NOT LIST TWO PARTS SO I DON'T NEED TO SPEND AN EXTRA $75-100!!! At time of writing this review, over a week since delivery, the website still lists the two parts depending on upper type with no mention of the manufacturing change.

If you've wanted to put a better rail or turn your BRN-180 into that SD tucked suppressor look, this is the adaptor for you. It's super easy to install and takes about 30 seconds to get the old handguard off and put this on. There's a little screw in the bottom that works just like how the original handguard does. Just make sure when mounting this, take out your whole piston before or you won't have enough clearance to seat the adaptor against the receiver. 10/10 product.
