Aero Precision Enhanced Uppers (10/02/2015)

I have found the enhanced uppers from Aero Precision to be well made and easy to assemble due to their construction. There is no guessing with the gas tube installation as it is separate from the barrel nut. You do have to use their hand guards or a BAR equivalent but the added strength of the upper just by its construction should make it last for the life of the firearm. I have three enhanced uppers ( 2 in 5.56 and 1 in 308) and had no problems with them at all.

One of the best free float systems (09/12/2015)

My dad and I both bought one for our AR builds we love it ... Fewer parts and super durable aero knocked it out of the park.

I really enjoy building with AP uppers! (25/05/2016)

How you use the product: I use Aero Precision M4E1 uppers and their gen2 lowers exclusively to build by 300 AAC Blackout 8" pistol, 10" SBR , and 16" rifle. The price is right!

Things that are great about it: There are cheaper, and far more expensive components out there, but Aero Precision means quality, customer service, and value to me. I'm loyal, full stop!

Things that aren't so great about it: my local gun store doesn't carry them, so I have to order online, but that's obviously not an issue with AP.

My most recent M4E1 enhanced upper and their new 15" Quantum MLok handguard purchase went into my latest 16" 300BLK. The upper was a blem but I couldn't tell where the blemish was. Whatever!

U can modify to work with AA XLP piston (02/05/2017)

I purchased this upper to make an Adams Arms XLP piston conversion work. I'm using with an 8.2" CMMG Barreled .300 blackout, with 12" Aero railed handguard, for a suppressor "under the handguard" build . The XLP piston kit gas block fits under most handguards, BUT requires a mil-spec barrel nut "length" in order for the drive rod to work. That makes it incompatible with most handguards that don't utilize a mil-spec barrel nut. ENTER THE ENHANCED UPPER! Aero says it's not compatible with pistons, but it is.....if you purchase a 3/8" diameter piloted counterbore with 3/16" pilot (buy online for about $30 delivered), you can very easily use the gas tube hole in this upper to pilot the counterbore and bore a recess through the first and second gas tube hole "fin", coming to rest on the face of the 3rd fin, (to yield a length equal to mil-spec barrel nut length). That recess will accept/capture the drive-rod bushing that captures the spring on the piston drive rod. You just have to take the bushing to a grinder and grind a small crescent of material off of one side of the bushing to make it clear the barrel nut, and.... PRESTO! you've got a rock-solid piston converted upper. Plenty of barrel nut threads left to not lessen reliable barrel torque, & no alteration to the barrel nut at all. This upper is completely solid and almost monolithically rigid when coupled with an Aero enhanced handguard. I like that I can remove it easily with the screws to maintenance the piston and suppressor if needed, since the large diameter of the hand guard will slide over everything. I bought it with the 12" railed hand guard so that a 1.5" suppressor will fit inside with lots of clearance to spare. I think this is a perfect solution to what I found to be a huge problem. (It saved me from giving up and returning my XLP kit!) I'll be purchasing a couple more of these uppers for use in precision rifle builds too, as I think they offer more rigidity to the barrel lock-up area, since there is a LOT more material than on a standard upper, to dampen harmonics and add rigidity to heavy/long barreled builds.
