제품 잘맞고 유격없이 잘 장착했어요. 아쉬운 점은 이너바렐과 프론티어 레일에 고정시킬 부품이나 오링이 동봉되어있다면 더 좋았을텐데 그부분이 아쉽네요.
배송이랑 안내 모두 친절하게 해주셨고 물건도 완벽하게 도착했습니다

RETRO ARMS cylinder head, A Standard is compatible with the general V2/V3.
The nozzle pipe length is 15.8 mm.
The body is machined from EN AW7075 and the cushioning is made from polyurethane. 
The cushioning material is 1mm thicker than the stock, and a gentle taper is created from the piston striking surface to the nozzle pipe.
This allows the compressed air to flow smoothly.
This reduces pressure loss, and simply replacing the cylinder head can improve initial velocity slightly.
Because the cushioning material is thick, the piston is set back 1mm compared to the stock.
When installing, please check for interference between the piston rack gear and sector gear.
Test Conditions
