RTP Rail and Barrel Lock assembly problem/question:

[SGranier]

Just picked up a RTP rail, and I pulled my old twist lock pin off another classic rail.

It's the same assembly right? I can only fit the lock assembly in about half way and then it gets stuck. I don't have a rubber mallet or anything to really knock it in there, but I never recall other ones taking this much force either. Is it just a tighter fit that I'd need to possibly shave down or open up the hole on the rail?

Or am I wrong and there is a completely seperate lock assembly for RTP rails vs. classic rails. I'm a mechanical engineering student and so I have a moderate shop that I can access with a pretty good drill press if necessary.

Let me know what you guys think. Personally I think I just have a slightly large pin assembly or slightly small hole in the rail.

Thanks,
Sean

Its the same assembly. They are press fit in there with an arbor press at the factory.

Rogue,

Which method should I use then to get the assembly in there? I'm unsure if we have an arbor press around the various shops. I'm sure I could rig up something push it in there. Maybe a vice and put a protective housing around the lock pin. Then just torque it up until it's in?

Shield and Hammer?
