Or not.

In reality our uppers are extremely well built with attention to detail paid to every step of the process.  We use only components that we are familiar with and have been using to great sucess for years.  We inspect and prep every part prior to assembly, then test fire and confirm accuracy with each unit. 

• 7.5" 5.56 NATO 1:7 nitride treated barrel
  • Chamber honed to improve reliability
  • Feedramps polished
  • Gas port pin gaged at .076" for optimal function with 5.56 ammo and a 3oz buffer
  • Bore and chamber inspected for defects and burrs
  • Headspace checked with PT&G go and no-go gages
• Azimuth precision ground BCG with 9310 bolt and billet extractor
• Aero Precision 7.3" Atlas R-One MLOK handguard

We test these with commercially produced 5.56 NATO loads and recommend you use only name brand new manufacture 5.56x45 ammunition.  You are welcome to use cheap steel case if you wish, but you will see a decrease in barrel life and reliability.  It won't void your warranty.  We will not warranty any issues arrising from the use of reloaded or commercially remanufactured ammunition. 

This upper is to be used on pistols or registed short barreled rifles only.  All NFA regulations apply.

Current Promotion:  for each upper you order, we will also include a Bad Attitude basic lower parts kit (no FCG, no grip, no trigger guard) and a Bad Attitude lower receiver of our choice.  The lower may be a slight blem or a perfect lower.  No choice of model or design.
