... In fact, the kit reduces your total part count on the rifle and isn't nearly as fragile or complicated as he reports.
I confess that I know virtually nothing about these piston conversion kits, so I am always open to learning more.
I watched the video and I saw all the new parts, that replace a simple gas tube. So I was wondering how there could be less parts with that piston than on a DI system.
The Osprey web site shows that you get 9 parts with the kit:
1- Op-rod
2- Piston Chamber
3- Roll pin
4- Carrier
5- Piston
6- Valve retaining clip
7- Piston retaining clip
8- bushing
9- Groove pin
This replaces:
Carrier with staked carrier key using 2 screws. It's 4 parts that are treated as 1, I never remove the key.
Gas tube
Roll pin
3 gas rings on the bolt, but I use a MacFarland ring, so one piece.
I'm thinking that saying there are less parts is somewhat misleading. In fact, 9 new parts really replace 4 old parts; to me, that makes it more complicated.
