Nickel boron Cera plate II bolt finished!!

[Deeked]

Might not have turned out so good because none of the people who had it done have responded with any sort of results. I would love to hear from someone that had cycling issues before the work so we could see if the bolt coating alleviated some of the problems.

I'd be interested in a range report as well - the idea of a permanent coating that keeps carbon buildup to manageable levels is an attractive one to me.

I've tried mine twice at the range so far and I'm having cycling issues. I will say I never fired it factory, and I did have rails/gas block/etc installed, so it still could be that. From what I can tell it's short cycling just a bit such that the bolt won't lock back and it won't quite pick up the next round although it will reliably eject. It seems to be getting closer to fully functional after about 40-50 rounds, but it's still not there yet.

But the bolt looks nice!

Honestly guys, I think the gas port on the barrel might be undersized just a bit causing cycling issues. Going to see if S&W will give me the Min Max diameter size for the port so I can check it and step it up if I can.

Thanks for the update - please keep us posted on your progress!

Read the posts by rojodiablo. You need to add weight to the buffer. It fixed my issues of "short cycling". Actually its not short cycling, rather the bolt is moving too fast before the next round can pop up. He explains it well.

My next range day is going to be the twentieth of this month if my membership is accepted for the club I'm trying to join. I'll have plenty of time there to give the buffer weight solution a shot. Thanks for the reminder. rojodiablo does know his stuff.

So far I've tried the standard buffer it shipped with, a heavy-short buffer that Rainier had put in, and the Enidine Hydraulic buffer all with the same results. Actually the Hydraulic buffer wouldn't even let the bolt be held back by the bolt catch at first but now it does.

I went to the other end of this solution, I added weight to the BCG

I wasn't trying to hijack the thread. On many of these guns, it seems the buffer needs more weight because the BCG is moving too fast. It just seems that if you do the nickel boron thing, it might move even faster due to less friction. That might make the need for more weight in the buffer more important. I'm not an expert with these guns (yet!) but this seems to make sense.

Not hijacked at all IMO. We are questioning the coating on the bcg and the ftf issues. The point you made is on point. If the bolt does move faster as a result of the coating and adding weight to the buffer helps with ftf's, then what you said makes perfect sense.

Finally got the bolt and carrier back from CCR Refinishing. They did an amazing job and the system is able to be run Dry , not that I would, and also makes cleaning a breeze. When I got the bolt back I could tell the smoothness and how sleek it was. Can not wait to finally break this in....still waiting on Troy hand guard.

How much did this run and what was the turn around time? It looks fantastic btw!

Well, today I got out to the range and I'm pleased to say that after adding some weight to the buffer my gun cycled everything I threw at it. Used the factory 10rd mag and 20rd pmags. I ran 6 different types of ammo including the troublesome cbc ball ammo and she ate them for lunch. I am one happy camper.

Thanks guys.

 

[ohbejuan]

How much weight did you add? What's the final weight? I didn't see the posts by rojodiablo talking about how to do this...

I tried a 5.4oz buffer with still the same problem

Deeked;

Did you have your bolt treated with Nickel-Boron, or were you having issues with your stock configuration?

 

[BW460]

If you search for rojodiablo you should find his posts on this. I did not have my bcg coated with nickle boron. I added a lead disk about 50 grains or so to the stock buffer. It cured all of my cycling issues. I don't know if the coating would cause you to need a little more weight. I cut a disk about an eigth of an inch off a 45 cal lead bullet and it did the trick for me.

Adjustable gas block?

For those of you with the upgraded BCG, are you running an adjustable gas block?

Ok, so it has been almost a year since I had my bolt coated. I haven't fired the rifle once until 2days ago. I was waiting for my friend who is sniper in the army to return from 4th campaign.

I was able to spend about 5 hours at the range breaking her in and I'm VERY impressed with the results. I first used 120 rds of PMC 147gr at 100yds and cycled every one with no issue. Then I used 120 rds of Tulammo 150gr at 600yds and had no issues at all. This rifle is amazing, my buddy was giving me wind calls shooting into full value 8mph wind and putting rounds into a 11" circle.

Cleaning was a super breeze and much easier than a stock bolt/carrier

Sorry about the delayed response but I wasn't shooting it until my buddy returned.
