Hello everyone,

Sorry if this is in the wrong section.

I recently ordered several parts from PWS and they were not up to my expectation. I was just curious as to your experience with PWS.

Today I received a 16.1" DI barrel, which was flawless except for a noticeable nick in the barrel that can be felt when you run your finger over it.

This is not the reason I post, as this is just possibly a manufacturing defect or happened while in transit.

The main reason why I post is as follows:

The buffer has reciprocating weights in it. I didn't expect them to be sliding around so noticeably, is that normal?

Lastly, with regards to their complete BCG, I received it and noticed immediately that the bolt is apparently stuck. It doesn't reciprocate and can't be removed.

I was curious if anyone has had any experience with this product from PWS.

Any tips on how to remove the bolt from the carrier? I can say for certain that there is absolutely NO lube on it. Could it be wedged?

I will update you to the progress of my situation.

Kind regards,

D

P.S.: I can provide pictures if required
 
The buffer weights absolutely should move! That is totally normal.

As for the bolt being stuck in the carrier, they can be quite tight, as the gas rings seal the bolt into the carrier body, and there may be some carbon residue if they fire tested the bolt. With the firing pin retaining pin taken out, and the firing pin removed, the cam pin should twist around and be removed with the bolt in its most rearward position. If it's stuck forwards, then pushing it down on a steady wood table should do the trick; then complete the dis-assembly and clean/lube and put back together. Generally you should have to flick the complete bolt group in your wrist before inserting the bolt group into the gun. They are not meant to be loose and sloppy, BUT it shouldn't require a ton of effort to move it back and forth. If it's tight it should loosen up a bit in the first dozen lock/unlocks.

If it's so tight that you need tools to move the bolt inside the carrier, then it may be some junk inside or the gas rings were misaligned or got crammed in somehow... In any case if it's totally locked up and penetrating oil doesn't work it loose, it may be best to contact the company you got it from about a return or exchange!
 
Sorry if this sounds silly OP but I don't know your AR skill level... Did you try to disassemble it? Are you using not able to pull/push the bolt in the BCG? I know some folks are afraid to use any kind of force afraid that they will break it. Give the bolt a good push/pull and see if it isn't just seized up from being in storage.

The rattling in the buffer is normal. Spike's buffers on the other hand use tungsten powder instead of weights so there's no rattling. Where is the ding on the barrel? Along the barrel or on the crown?

Ya it is completely locked up from what i can see. I took out my BCG from my DD and it is normal and everything moves as it should
 
So you cant charge the rifle by racking the charging handle? My guess would be some loc-tite leaked down from the gas key bolts onto the bolt and has locked it up, use some muscle on it.

The BCG hasn't been installed yet. I noticed that the bolt was stuck when I took the BCG out of the package.

Nobody uses loctite on the gas key screws. There's way too much heat in there for loctite to hold up to. Use some muscle on it as Estrada pointed out.

You won't hurt the bolt unless you're using a wrench or something.

You can try putting the bolt HEAD into a padded vice (wood or leather to pad the bolt lugs, and ONLY tight enough to prevent it from spinning at all, you don't want to crush the locking lugs) and then HAND-spin the carrier while pulling it up. (or push down if you're trying to get the cam pin out)

If it doesn't move under hand power (you can use 2-hands on the thing) then I wouldn't try anything else aside from soaking it in penetrating oil or a solvent or something to try and clean it out - and trying again...


At my last job, we had some Ti-N coated bolt groups come in, and the Ti-N coating was on WAYYY too thick on a couple of them, and the bolt heads were so tight in the carrier that they wouldn't move. Because the manufacturer was such a PITA to deal with for export (not to the USA) we had to fix them ourselves, and it required a polishing buffer on a drill and polishing compound....

But to get the bolt head out initially, we put the head into a padded vice and hand-torqued them to get the cam pin out, then torque and pull to get the bolt head out of the carrier.

Thanks for the input!

I'm currently dealer with the authorized Canadian dealer for warranty. We'll see how it goes. So far it's been great from that perspective. The PWS parts have definitely not lived up to their expectations. Hopefully once this is righted, I can walk away smiling.
