BCM的回复：

"We pin the gas blocks when they are fully exposed (like a Mk12 Mod 0 type build), but when the gas block is protected by the handguard we don't pin them.

However, with our method of proper install; its about a 15 minute procedure with MAP gas to remove a BCM installed gas block. It is NOT coming off by accident. "

但是后面有人说，几十秒就拆下来了。。。

我去。。。只能打打看了。

既然他们从来都是这样搞，不是个例，应该不用担心，要不然早就名声倒地了
