Ramp Job & Re-Cut Services primarily help with reliability with wide ranges of Ammunition and certain Projectiles such as Soft Point, Ballistic Tip, and Hollow Point. Often AR15's have Feed Ramps that are rough, or worse are "Clickers". A "Clicker" Ramp can be identified with a Ballpoint Pen. You run the Pen tip up the where the Upper Receiver Stops and the Barrel Extension Ramps Begin. If the Tip hangs up you have a "Clicker". This usually results in a Failure to Feed Malfunctions with certain Ammunition. A "Clicker" can also force a Projectile to be forced into the Casing which can increase Chamber Pressure dramatically, which is far from ideal.

This Service also keeps the Locking Lug Area and your entire Weapon from accumulating Brass Shavings which can affect reliability. Polishing the Feed Ramps minimizes rough areas that shave material as Ammunition pass over them. If enough Brass/Copper Shavings accumulate the Bolt will fail to rotate into battery and will result in malfunctions. Alternate Benefits include reducing Brass Casing Damage. Reloaders tend to appreciate this added benefit. Effortless Feeding and Proper Ramp Geometry also minimizes Bullet Deflection when Feeding & Chambering Rounds. Projectile Deflection and Damage can affect the Weapons Accuracy & Consistency.

 

This Service allows the Weapon to cycle easier when Clean or Fouled, allows eased Chambering, decreases Brass Casing Rim Damage.

 

 

 

*Tune Extractor and Ejector System $50.00 Labor (Extractor NOT INCLUDED)
NOTE: Includes
New CS Ejector Spring
New CS Extractor Spring
New Extractor Insert and O-Ring

*Polish Bolt Group Assembly $65.00 Labor
NOTE: I can NOT perform this Service on a Un-Shrouded Bolt Carriers, Nickle Boron Treated Parts, Hard Chromed Parts, or Notched Hammers. If you have a Notched Hammer we can install a Milspec Rounded Hammer for $25.00. If you have an Un-Shrouded Bolt Carrier we can provide a M16 Carrier for $95.00
NOTE: Includes
We De-Burr Firing Pin Hole
Check for Binding with the Firing Pin
Polish Hammer Face
Check for Free-Float between the Firing Pin and Cam Pin
Contour and Polish the Extractor contact surfaces
Polish underside of the BOTTOM 3 Bolt Head Locking Lugs. This keeps the 3 Lower Lugs from Gouging and Scraping the Rounds in your Magazine when fired or hand cycled, thus a cleaner smoother Weapon System
Polish tail of Bolt Carrier. This eliminates Receiver Extension damage and Buffer Damage
Polish Buffer Spring ends. This prevents Buffer Tube Friction/Galling
Polish underside of Bolt Carrier. This reduces Hammer/Carrier Drag and reduces Short Stroking probability when lube is thin/absent or when heavy fouling occurs

 

We Polish and Contour the Extractor. The Polished Extractor Face eases Round Chambering, and minimizes Casing Rim Damage. The De-Burred Firing Pin Hole decreases the likelihood of Misfeed Malfunctions.
