Description

Kit of parts for AR15/M16/M4 frame (only models fitted with an M4 type telescopic stock) comprising:

• 1 X-tra Power recuperator spring (“carbine” length for M4 type telescopic stock, not compatible with the fixed stock of the A1/A2/A3/A4) (this spring is 10% more powerful than the original to ensure a better return battery, increased reliability and reduced recoil)
• 1 Recoil spring buffer (“carbine” type for M4-type telescopic stock, not compatible with the fixed stock of the A1/A2/A3/A4)
• 1 hammer spring.
• 1 Detent spring.
• 1 Telescopic stock tube nut (“Castle Ring” type)

Note: the “Castle Ring” type nut requires a key that we generally have in stock.
This wrench takes 3 of the 4 notches in this nut for optimal tightening.
This nut is the evolution of the old telescopic stock nut which previously required a much less practical pin wrench.
