Mongoose

I have installed a M140 spring and it work without any problems. Only problem was installing the spring. You need 3 hands for it.

I have know idea. I don't know this foregrips. Sorry.

I have no problems with it. Depends on arm lenght and -strenght. Besides, I am aiming lying down most of time anyway.

Yep. You can take that handguard away without any hassle. But you can leave it on. Even with bipod connected, there is enough space left between hand guard and bipod to place a foregrip.

Need I say more? :wink: Yes.. Some additional info: This EBR kit is a *badgeress*. It comes along with a instruction CD that is not really helpful. Beside that some of the M3 holes were of very poor quality and I converted them to M4.
