ZRTS Ultimate Package for GSG and SIG 1911-22

Hands down, this is the best upgrade for any GSG/Sig 1911-22.
Includes:

• Full length guide rod
• Slide alignment cone (SAC)
• Bushing
• Spring
• Plug

Replace your short, plastic factory guide rod with a full lenth one made from stainless steel, ensuring smooth operation and eliminating the factory "crash" issue.
The stainless bushing replaces the zinc die cast factory unit, effectively eliminating the chance of breakage.
The Slide Alignment Cone (SAC) perfectly aligns to the bushing providing a significantly tighter fit for the barrel in the bushing.
The high performance spring is optimized for high velocity bulk pack ammo.
Comes with a high density buffer for optimal performance.

Note: This package eliminates the need for the barrel retaining screw.

ATS personally recommends this product after thousands of rounds of testing.
