Airsoft PDR Rifle by Magpul Review

Check out the airsoft PDR review on Youtube.  I heard it’s coming out in the next few weeks.

Playing during the winter

How cold is too cold to play airsoft during the winter?  Luckily it doesn’t get too cold in the south.  Where do you play at?

Double gun bags at Airsoft Atlanta

Wow, very cool bags that fit most M4 and M16 rifles, AK-47 rifles, and airsoft guns under 36 inches in total length.  Holds two carbines/rifles!  For the money, this is an excellent gun case that everyone should buy to store and transport your gun with.

 Step 2: Installing Cylinder Head Damper

• Clean the cylinder head and damper with mild soap and water, then dry them with a paper towel.
• Apply CA glue (super glue, crazy glue, etc.), to the cylinder head rubber directly (figure 1).  Fully coat the surface to which you’ll be applying the damper.  Be careful not to get any glue on the o-ring(s) of the cylinder head.
• Align dampener and place it carefully onto the center of the cylinder head (NOTE: once the dampener come into contact with the glue, it’s nearly an instantaneous and permanent bond, so treat this like you only get one shot at it).
• Check for good alignment.  You should be able to look through the front of the cylinder head (stem) and see clearly though the hole. 

Angle of Engagement 101 – Sorbothane Airsoft

Angle of Engagement 101 & Sorbothane Damper installation for airsoft gearboxes.

Goals:
• improving piston wear / strength allowing for higher rates of fire, higher tension springs, or both
• preventing gearbox shell breakage
• quieting the piston stroke

Introduction: When someone talks about “angle of engagement” in an airsoft gearbox, they are referring to the angle difference between the first tooth on the sector gear and the first piston tooth. (Figure 1) The better aligned the 1st sector tooth is with the 1st piston tooth, the likelihood of piston and gear failure is reduced. This allows us to run higher tensions springs and / or higher rates of fire with more confidence.

To modify the angle of engagement, you can attach a sorbothane damper to the cylinder head. This will cause the piston to rest slightly toward the rear of the gear box, improving the angle of engagement, deadening the sound that the piston makes when it slams forward, and reducing the shock to the gearbox from the piston strike. This only works on cylinder heads with flat striking surfaces. The cylinder heads with chamfered or beveled striking surfaces (e.g. SystemA silent piston & piston heads) are not compatible with this technique. Cylinder heads that will work include SHS, Guarder, and Modify version 2 and version 3, as well as others with flat striking surfaces.

Step 1: Checking for Angle of Engagement
• Remove tappet plate, nozzle, and other parts that may get in the way
• Push the piston (with the piston head installed) forward in the cylinder
• Rotate the sector gear counterclockwise until it contacts the piston
• Check for angled (Figure 1) or flush engagement (Figure 2)
