其實步槍既Rail有咩用

可以加呢樣果樣,搞到支槍奇奇怪怪咁
Rail除左可以加野,仲有什麼好處?

Actually, there is 1 major effect even the P-rail system developer never imagine it will achieve beside adding accessories.

The P-rail is keeping the barrel from breaking from overheat by allowing ground to expand and cooling directly from the P-rail system.

It work as a reinforcement of the barrel on top of the handguard.

俄羅斯的步槍有Rail嗎?

They have, not P-Rail system thos is called weaver rail

Rail是金屬,會令手受傷嗎?(割傷)

No, it was oxidizetreated, it is same as any metal furniture using in your home, will you table cut you open? I don't think so.....

Rail既主要用處就係加裝配件,其餘都冇乜用嫁啦= =
俄羅斯的步槍冇加裝Rail
但都有人將AK系列加Rail
當你大動作時Rail都有可能割傷自己
但使用時通常會戴上手套
所以冇乜影響
