WE PDW Gen.3 Airsoft GBB Rifle Part #123-125 - Complete Bolt assembly w/ Nozzle

"This part is a direct replacement and works perfectly in my EMG PDW M2.

This part: http://www.evike.com/products/42446 is perhaps a better choice because it has the original nozzle style (not the aluminum nozzle by RA-tech that doesn't work), and it has an NPAS. If you want to try the NPAS, go for the whole assembly and don't waste your time like I did with the aluminum nozzle. Either buy this one that has no NPAS (like I did to keep the gun stock and performing normally) or buy the NPAS full assembly and find the sweet spot where the gun still cycles. Again, stay away from the aluminum NPAS pre-assembled nozzle, I left a good review for that but it's actually a defective product.

This product works fine on the other hand, and I would recommend it if your blue nozzle broke and you want to make sure nothing else is wrong with your gun.
