All that matters is it has the appropriate thread for your gun and that it's not heavy as that will effect the gun cycling. other than that go for which ever one you like the look of.
Craig is just doing what Dalton did 20 years earlier. not saying thats a bad thing but Dalton does get the credit he deserves his bond was too soon for the time.
I don't know if this actually good value i don't up grade guns but why would you put this much money into a £110 gun that is one of the best out the box performing guns on the market?

couple of places have it sub £300 but the price seems to have snuck up everywhere else. still maybe pay £240.00 for a2nd hand one with no extra mags. I sold my 3 month old with 4 mags for £280.00 how i regret it.
