SCAR with possible broken bolt catch

[ranygamer]

So i'm pretty sure i need a new bolt carrier.

The first photo shows that chunk of metal has fallen off and the second one shows that the metal on the block bit has actually bent inwards. (Although it does not effect or damage any other internal parts)

I'm looking at getting the RA-Tech steel bolt, but at £120 i'm a bit skeptical. Anyone here ever tried it? or would it be better to get a stock WE bolt carrier, if you can?
