Great quality!!

by

Great upper! Finish is amazing and it runs with any kind of ammo. I have yet to have any issues. Very we'll made. The firing pin and bcg is topnotch and only adds to the quality of FM products! And their customer service is icing on the cake.

These uppers will definitely get all your friends attention

Absolutely gorgeous!!! I purchased two of these uppers and these things are hands down the best. I love the side charge feature towards the front. They’re light, slim and fits in your hand so natural that it’s just a good feel. Their made well and you can tell when your holding it. Just a really good product. This guy is on to something with these uppers and even though I’m not a competitive shooter I can easy see these uppers being run in the competitive world. They are fast!!! I’m very happy with my two uppers and everything else I’ve got from FM-products for that matter.

Best 9 mm Uppers and Lowers on the Market.

I have purchased two different Side Charging uppers.<br>This one is the Best I have seen and used. <br>My 1st one, from another company, you had to unscrew the side bolt to clean the Bolt Carrier Group, and the knob comes loose while shooting when you continue to screw and unscrew the side charge knob to clean the bolt Carrier group.<br> On the FM version, the side charge knob up toward the front does not need to be removed to slide out the Bolt Carrier group for cleaning. <br>Also, FM products has great customer service, I also bought there lower and they sent me spare parts until we had running like a Swiss watch. I highly recommend their Billet lower with any 9 mm upper.<br>Love this Company.

Will not fire Winchester

I don't know if I have a bad batch, but it wouldn't fire Winchester ammo (brass or steel case). I have a stash of Winchester and Federal ammo from Walmart. This will fire Federal rounds. I even mixed Winchester and Federal in a magazine, and it will not fire the Winchester at all. Not even a dimple on the primer of the Winchester. Even after FM sent me a new firing pin, it will not fire the Winchester.

I matched this 8.5 complete upper with an FM billet lower and have to say I'm very impressed! The quality is top notch and the forward charging handle is sweet! I've put about 500 rounds down range so far with not one failure. This gun thus far has exceeded my expectations! The customer service is top notch as well from both PA and FM.

I used this 8.5 complete upper matched with the FM billet lower and couldn't be more pleased! The quality is top notch and the function has been flawless! Go FM Products you won't be disappointed! Forgot to mention the customer service is also outstanding from both PA and FM Products!

Would I buy it again? HELL YEAH! I've already started stashing a portion of my paycheck away so I can buy the 16" upper without the wife noticing.

There's not much to say... this upper receiver is BAD ASS. Quality of construction is the best I've seen and rivals more popular and more expensive 9mm upper receivers. <br><br>I've paired this upper with a Ranier Arms lower fitted with a CMC AR-15 match flat trigger and a Sylvan Arms 9mm conversion block. <br><br>IT FUNCTIONS FLAWLESSLY!!! NO TUNING, NO ADJUSTMENTS, just swap upper, insert mag block and mag, chamber a round and you're ready to rock. <br><br>The blast diffuser is neat. I've never used one so I'm not sure if it's working the way it's suppose to, but it doesn't seem to affect the function at all.
