Solid handguard for the price.


Solid handguard for the price. Went on easily and feels very solid yet lightweight. I used it with a 7.5” barrel and a KAK micro flash can. Looks great. Seems to be very well built and aesthetically Pleasing as well. I contacted Stern with questions about the exact dimensions and they got right back to me with detailed information. This company’s products are a value for the price. I hadn’t heard of them before buying this handguard, but will definitely consider them in the future!

Spend a tad more, get a better part


There are several issues with this item. 1) No printed instructions. 2) The barrel nut does not fit a standard AR barrel wrench, you must buy one from Stern. 3) Unlike better designed hand guards I've installed, this barrel nut must be indexed such that the gas tube will fit into one of the slots in the barrel nut. Mine hit almost exactly half way between slots, meaning that I needed barrel nut shims, another $4.99 from Stern. You need to factor in another $20+ in parts and shipping, plus the wait for however long it takes to get to you. Fourth, the barrel nut appears to be parkerized, which I hate. I spend good money buying barrels and accessories that are melonited as they are far more rust resistant than parkerized parts. This barrel nut is likely to rust and it is difficult to get to keep rust preventative on it. Shame on Stern for not including the proprietary wrench at least, and shame on Palmetto for not disclosing the lack thereof on their page offering the item for sale.
