This upper looks great and fit my lower perfectly. The customer service was excellent in helping me find what I wanted. This is my second order here and both have been great!

I researched the company and determined this was a rather well established business. Customer reviews on social media confirm this with the exception a few negatives because the customer didn’t bother educating themselves on cancellations.
From point of sale to delivery was about 5 days. The upper is amazing from a fit and finish perspective. No burrs or machining marks. The anodized finish was very nice. The Handguard has become my favorite in my collection against AP and BA setups. I set this up with a Geiselle BCG and everything spec’s out perfectly with a set of Go/No-Go gauges.
Very happy customer. Will be back.

Well put together and looks nice. My second upper I’ve purchased from BKing.

Haven’t had a chance to shoot it but looks like quality work. Handguard had a few scratches but I touched it up with a black AR marker. Had a few questions about shipping times and customer service was extremely fast getting answers.

Totally stoked on this upper. This upper fits great on all my lowers with no slop or wiggle. Loving the profile on the rail. I plan on buying the same set up with a shorter barrel/rail down the road.

Quality product from BKF! The real estate on the FFSSR is great and does not tear up my delicate hands. MOD-0 is the way to go!

Ran 500 rounds of PMC X-Tac 5.56 through it with zero malfunctions. Quality is very good, couldn’t be happier with my purchase.
