I have a Vector 53 that I run a registered sear pack in. The bolt gap is less than .008 which is the thinnest gauge I have. Gun functions fine but the rails about 1 inch back from the trunion are getting small dents in them on both sides. I've been told that improper bolt gap can cause dents in the rails but that occurs farther back near the rear of the receiver rather than in the front as mine is occurring.
One other item of note is that the barrel, cocking tube and possibly (?) trunion are not aligned down the long axis of the reciever. It has an upward tilt to it. I have seen other guns with the cockeyed barrel issue from Vector. I contacted Vector about the barrel/ cocking tube misalignment and they gave me the run around saying it was normal and cocking tube and front post not evenly spaced was not an issue and that essentially if the gun cycled there was nothing they are going to do. I have been wondering if the dents are because the misalignment is stressing the bolt and causing the roller pings as it unlocks. Any thoughts?

Check your locking piece. Mine was re-ground by vector and I couldn't get bolt gap in spec.

I replaced it with a real HK unit and bolt gap was immediately in spec. It also ran correctly with the sear after the swap.

Thanks I'll check that out

Thanks I'll check that out

Compare your locking piece to a factory #15 to see how it was marked. Most of theirs had ground shoulders and were remarked. I would just order a new #15. Your timing and gap will be better. Sounds like your unlocking too early and slamming the carrier into the buffer.

I just ordered a new Vector V53 from them a few weeks ago. Sent it to Jeff Walters @ PCS, and he is fixing it for me, in addition to engraving NFA info and refinishing.

I dont know what date yours was built, but after learning from Jeff and seeing how it was put together, I understand why it was $1,100 new.

The locking piece has 15 stamped on it, but does not look like the markings on the HK factory G3 carrier, which appears to be laser etched. I think I will do as you suggest and just order a new one. Thanks

I bought the gun in 2008. Receiver has the rounded rail bends vs the squared rail bends on factory guns. I think the trunion Is Hk but everything else is aftermarket clone or maybe some Hk licensed stuff from 3rd world parts kits.

Mine came with a reground LP, stamped 15. Functioned fine, test-fired 200rds through it with 0 issues. However, recoil rod was messed up, couldn't get the handguard pin in it once I took it out. The only time I was successful, I had to use a lineup pin and a hammer to hammer it in. Jeff said it's a Todd Bailey barrel, with a different length cocking assembly, so the recoil rod, and cocking tube support are both custom-length. I asked Vector why they weld the front sight to the barrel lug, and they replied "Thats just the way we do it" Jeff noticed when he pulled the front sight off, to fix the hanger, that they'd re-pressed the barrel once before, as it had channels for the sling pin on both top and bottom of the front sight lug.

So Jeff is reinstalling cocking tube hanger, front sight, dust cap. Also engraving NFA info, refinish and pinning the trigger group. Total cost for all the work, and return shipping was $600.

Can't wait to get it home and see it again!
