Worker Metal Internals Kit for Nexus Pro (Two Colors)

Great construction overall, definite quality upgrade for my Nexus Pro. However, the dart fit is not quite as tight as 17/32" brass, and it's slightly expensive for what it is. Probably needs to be paired with the metal priming kit in order for a very heavy spring to work. Works exactly as advertised.

I bought this along with the priming kit, one of the o-rings came damaged so I had to replace it. The blaster shoots harder than ever over 230fps with DZ short darts and a 16kg spring+OOD budget spacer. The main reason I bought this was because my 17/32 brass had been punctured and the metal breech allowed for more airflow than the OOD skinny breech I had purchased last year. so I thought, “might as well just upgrade everything.” and -$110 just like that. NOTE: My aluminum barrel did not come with the short orange barrel wrapped around it and I still cannot figure out what that does, if anyone knows please tell me.

This is absolutely amazing, installs so easily too. And the performance gain is very good. Highly recommend this. Got too purchase the other kit that goes with this kit. Both together make the ultimate nexus pro. With both kits and spring upgrade I have my nexus shooting at a average of 250 fps and it is super accurate with excellent range

i like the kit, it changes how the blaster feels in that it's much heavier and feels more rigid. my only gripes are that the metal priming kit doesnt come with the rest of the pusher, so you either have to use the stock pusher or buy this kit as well. also, i noticed a couple of things that other reviews have mentioned such as the plunger being slightly too small to seal in the air chamber, though a little tape can fix that fairly quickly. also, i painted my rail and the front rail extension was a pain to install, but that was my fault, not the product's. all in all, a good product especially if you plan on doing other things to increase it's power, and the metal priming rod from the other kit is almost essential despite the installation snafu.

Overall it's a amazing kit, my darts are firing much more consistently and I'm very happy, however occasionally when a dart chambers it will get stuck in the barrel and destroy the dart, it's not frequent, but frequent enough for me to mention it, overall very happy with it though
