B14 R Bergara still buggy ?

What's wrong with yours?
Mine runs like a Swiss clock and shoots tiny groups.

I had an early B14R with the bolt that had the square cut in it. A simple but stupid design oversight.
Mine cost me about $975.00 and ran perfectly. It also outshot my V22, both in my hands and
while at Lapua. I always thought that it was a good value for the $$. My only real complaint was the trigger.
It's a sealed unit that can't be worked on. I have seen guys add a 4-40 set screw as a sear adjuster but after
I opened up a trigger, it was painfully clear to me, that that was not only folly but downright dangerous.
The MIM parts have rounded edges. I installed a #6-32, long nose spring plunger to negate some of the
factory spring rate and act as a sear adjuster. That worked but, that produced other problems with the safety
spring and caused things to bind. The B14R should only be replaced in my not very humble opinion.
My V22 had a TT Diamond so I put a Jewel HVR in the B14R.
I hated creep in that HVR unit. My next trigger will probably be a Bix & Andy Tac Sport with interchangeable blades.
I will very likely get another steel barrel B14R.

Mine (2022 manufacture) has never been buggy. Thousands of rounds through it now, no issues at all in either a KRG Bravo or Aero Solus chassis. I was using Vudoo polymer mags for a while but switched back to Bergara mags since they seem to be more durable.
What's the square cut you're talking about? Curious if mine has it or not.
My rifle will put the empty cartridge in place to lock up the bolt. When trying to extract, the empty won’t properly eject. It is an early model. I would truly like one that works. Bergara should man up and replace the rifle. They won’t even communicate now.
I have a 2019 steel B14R with over 15,000 rounds through it. I am trying to understand your issue.
Are you saying the round doesn't eject and falls down in the breech? If so it needs a stiffer tensioner spring mod. I use butane lighter springs. They fit inside the OEM tensioner spring. Cut to same length as OEM and reinstall. Holds empty tighter to bolt face, allowing ejector to kick it out instead of falling off going over the mag feed lips. I have done this to numerous B14R bolts.
Another thing is check for ejector wiggle in the receiver, some do dome don't. Popular is staking the ejector, I just wedge a piece of plastic tywrap in the space behind the ejector, looking from the bottom of receiver.
Now all that said, just bought an new B14R SS Heavy barrel. Have put near 1,000 rounds though it in the past few days. None of the above mentioned mods needed. Ejector solid and tensioner holds empty tight against bolt face. This one made 2024.
If you have already done the tensioner and ejector mods, and still doesn't function to your satisfaction, I don't know what to say.
I personally know of over a dozen B14R rifles, and those that have had issue, I was able to rectify by the above mods.
Good Luck.
Pom, Im glad you asked. It forced me to search my files and fix them. From my file extension, I can see that
my rifle was 2020 or prior. If you disassemble your bolt, you will see a square cut like my 2020 or a revised round bottom cut. Square cuts should be avoided because they lead to Von Missis stress concentrations that lead to failure due to high stress in that sharp corner.
In the B14R design, when the bolt is withdrawal usually with some authority to eject the spent case, the large black
front section hits the bolt stop, but the rear handle section tends to continue because the human is still pulling on it. That energy gets transferred to the thin side of the square cut out, and into the sharp corner.
Bergara replaced the square with a proper radius at some point. Image #4 shows what I refer to as a Dog Bone.
Take note of its radii. It's a heat treated, high stress detail. #5 has small radii as it transitions from the large to small
diameter. Just for fun, I have included a sharp corner FEA. They are great tools to put the customer at ease since anyone can look at the pretty colors and get a feel for what's going on in the design.

Bergara has had failures at the sharp corner, and it is a very poor design practice. But my 2020
has never had any issue at all. She was a great rifle, or I wouldn't be looking at another one.
This FEA shows a proper radius to minimize corner stress. It's all a very pleasant blue and green.
Radii need not be large to avoid the Von Missis stress concentration.
Image #4 is my B14R in my MDT LSS Gen 2 chassis that my V22 normally lived in. I also installed the Trigger
tech Diamond. The cool but $$ chassis didn't help with accuracy at all. The TTD trigger is very nice.
Given the choice, I would really like an IBI, 22" Shnooble barrel like image #3. I like the swell at the muzzle.
If memory serves me correctly, image #2 shows the correct orientation of the internal bolt parts. The shim
spacer is already on the black section of the bolt. My rifle was factory stock with no mods. The ejector did have
some lash, ( wiggle ) of about .003 side to side and about .020" for and aft. If the case pulls the ejector rearward
at the moment of ejection, why would I care if it moves?
A B14R SS Heavy barrel action would also be expectable for $609.00

The ejector is loose. I will give the lighter spring a try . Also the zip tie. I really hate getting a punch and hammering .
Don't just use the lighter spring, it goes inside the OEM spring, double spring. This has corrected many that didn't hold the case tightly enough to the bolt to allow ejection.
I also use an elastic band on the bolt handle to the front comb post. This primarily to prevent the bolt moving forward during transitions in matches.Thus causing jams or ejection of loaded rounds when pulled back. With enough band tension, I just lift the handle and let the band pressure eject. I don't even have my hand on the bolt after total lift. Ejection is positive with cases throwing a couple feet out and forward at the 1 o,clock. The band material I use is 1/8" elastic cord from Walmart, in the sewing section. I know others have used rubber bands and 1/4" flat elastic. I make a small loop on each end using a surgeons knot and one overhand knot in the middle to go over bolt handle. Trial and error on the cut length, but I think it's around 8" before knots.
Again, use the butane lighter spring inside the OEM tension spring, both springs.
The tensioner is the hook on the left side of the bolt looking back to front. IMPORTANT: Remove pin from the TOP of the bolt, the round surfaceas the hole is tapered. Be careful with the pin once removed and insert the small end first. Using a Q tip shaft (or something of similar size) to help align the hole and tensioner on reassembly helps. Don't force the pin back in, it will "fall" into place when properly aligned. Some bolts allow the pin to protrude the top of the bolt, make sure pin is recessed both sides so no drag in receiver. Newer bolts have a stop shoulder on the top prevent protusion.
And again, good luck!
Well I'll be darned, just checked mine and the bolt stop sure does impact on the bolt nose. I hadn't thought about it before and just assumed it would hit the locking lug instead. Still need to disassemble my bolt to see if it's properly radiused but at this point after thousands of rounds it's probably fine.
Only mod I’ve done to mine was just a switch of existing parts.
There are 3 springs roughly the same size but of different size wire and therefore different strengths.
The strongest is at my extractor hook (nearest the ejection port), the mid strength one is at the tensioner (opposite the ejection port), and finally the lightest is the firing pin return spring.
Since making this change I’ve had zero functional issues in over 10k rounds.
Mine was made in 2019, and currently rests in Berg’s own BMP chassis.
What is all of this talk about the B14R being “Perfect”?
Is the extraction still an issue on many of them?
Is the bolt still extraordinarily difficult to close?
Are models still experiencing severe galling on the bolt and lug abutments?
Because the rifle I received in 2021 was so bad on all accounts that I sent it back to Bergara.
They sent me a brand new barreled action.
I was a frustrated with it that I sold the damn thing. It sucked, period.
I do not understand why people are talking them up.

Extraction has never been an issue on mine. Last match I shot, a couple Vudoo guys had bad ejection issues. Neither of the Bergaras on the line did.
The bolt has never been difficult, let alone extraordinarily difficult, to close. It feels different than many other guns, but different isn't inherently bad.
Mine doesn't have any galling on the lugs. Recently that seems to be more of a RimX problem.
Why wouldn't I talk mine up, when it's been a fantastic gun for less than a third of what Vudoos go for? Sorry you had a bad experience, similar issues are why I'm not a CZ 457 fan even though most people seem to love them.
Yup, the ones that feed through an opening and lock in place, also called Cable Zip Ties.
Try calling them 877 892 7544 (8:30 - 4:00 but closed at lunch 12:00-12:45 - Eastern Time Zone).. I had similar issue, gave them a call, they sent me new extractor/holder/springs/pins to replace at no charge. There are some video's on replacing the parts if you need help. I've only been able to shoot a couple boxes of ammo since changing the parts, but zero malfunctions so far. The Customer Service lady I spoke with was very nice and supportive.
Well, the little dimples worked wonders as far as not getting the case behind the feed lips. Now, I need to get it to throw the empties with a little force. I will call them about the parts. I did have a misfeed with a green tag cartridge. It seems I will have to tune the magazine. I have a couple of more mags to try. The magazine fits very loosely into the well, with a lot of side to side motion. I just took and pulled up my big boy shorts, and got a punch and a hammer and staked that ejector.
