I have heard horror stories about the trigger groups going to shit in the closed bolts and the back plate breaking is common as well.
I was told this from a retailer so I trust his judgment that's thing still makes me want to go out and buy one. Looks sweet man.
Keep us updated how it functions.
This is the open-bolt version! Yeah, I've looked into the back plate thing as well, but it only seems to be a major issue if the bolt system is upgraded to a heavier bolt, in which case I'd just buy the metal back plate.
Thanks for the feedback! The R/G dot and vert grip are just leftovers from my last project. So far they function relatively well, so I'll keep them until I have the money to replace them with something prettier. As for the other things, Dahm, I'll look into them. Thanks.
