Trent's Review of Aero Precision M4E1 Threaded 20in 5.56 w/ ATLAS S-ONE Handguard Complete Upper Receiver with Flash Hider

It looks great. Fit and finish is good, but the accuracy is underwhelming especially with lighter weight bullets. Similar uppers are less expensive and so despite Aero Precision's reputation for quality, I can't say I would recommend it.
