Quality machining, meets up with AP M4E1 lower perfectly. Not sure why they included the nylon tipped tension screw, no jiggle… none. Barrel nut screws tight and lines up perfectly. BCG slides in tight without any resistance or gravelly friction. Holds the charging handle tight, again, no jiggle. Light weight, perfect finish with the cerakote. Worth every ¢. Thanks PA for the hook up, my 300bo pistol is looking/feeling smexy.
Primary Arms ROCKS! Aero Precision is Awesome

To Whom this is of interests: <br>This IS my 3rd: M4E1 SLICK Sided Upper, of which the 1st "2" I bought straight from Aero Precision. The 3rd, "M4E1 Upper" I found here on Sale via Primary Arms.. I had forgotten I bought the FDE, Flat Dark Earth Cerakote and I've got to say, it's an Awesome finish!<br><br>I choose the "M4E1 Slick Sided Upper" over the "AR15 Slick Sided Upper" because to Me, the M4 Upper looks like it is Stronger than the AR15 Upper!<br><br>Lastly, I Dislike/Loath the "Forward Assist" So Much, I got rid of all my AR15 Uppers that >had<LOL<>Get it?< Had a Forward Assist, to which one of them was even a Seekins NX15.<br>So now, ALL My AR15s are rebuilt as: Jim Sullivan & Eugene Stoner Desighed, NO Forward Assist!<br>Peace

This is my 3rd Aero M4E1 Slick Upper, 1st 1 from PA., the other 2 I bought directly from AERO... I despise/Loath the "Forward assist" and I have slowly switched out my AR15 Uppers to make them as Jim Sullivan & Eugene Stoner intended! <br>I was super surprised when I opened my box from PA., as I had forgotten I ordered the FDE, it's Awesome!<br>I have some standard Mil spec AR15 UPPERS if anyone wants to buy them? LOL<br><br>Peace WannaBee
