I was wondering if anyone else was having issues with their HS stocks?

What's happening to mine is the sling studs are seeming to have issues with cracking, breaking, and rounding out their mount:

This has happened to me on my .308 Rem 700 SPS when I bought the stock aftermarket, it was new, I sent about 300 rounds down the pipe before it snapped off in the stock from the aluminum mounting block in the fore stock and thus egging out my sling stud hole.

The 2nd occurrence was on a never fired Savage LRPV in .260 rem, I sold the rifle without ever shooting it (brand new in box), and the fellow who bought it from me noticed a crack coming from the sling stud, he fixed the issue with an Anschutz type rail (which I payed half for because I told him it was in perfect condition when I sold it)

The third is now on a 700P in .338 Lapua that I have purchased used off the EE, I can clearly see that it has been repaired (decently, but not disclosed) with epoxy from what appears to be the same issue I had with the .308

I guess I am wondering, is there something we are doing wrong and is this common? I can say that I like the ergonomics and the accuracy that comes with these stocks, I know the bedding block is the real selling point on the stocks, but shouldn't we expect better quality for 300-500 dollars depending on the model of stocks???
 
I haven't had issue with mine however I did mount a rail for the bipod to attach to.
Though it was for more solid then one point which it has been, maybe an option?
 
They are called "sling" studs for a reason. They were never intended for the thrust and forces applied by mounting a bipod to them. With the manner that the HS stocks are made they seem to be worst for studs shearing off than other fiberglass stocks.
The only real cure that I know of it to mount a short bit of rail to the stock.
Also some bipod attaching methods, particularly the Harris design, seems to make this problem worse than what some of the other systems do.
 
I have seen this problem on several HS Stocks. Some of these were on issued rifles deployed in the field, not acceptable in my opinion for a working stock. The majority of the swivel studs were loose. I have also seen sling swivels studs break off. I spoke to Donny at HS precision and he said they were aware of this issue and it had to do with steel swivel studs screwing into aluminum. Well if you know there is an issue, fix it. Its funny I never had any issues with swivel studs on any of the McMillan stocks I have used. I don't think the swivel stud is the issue, they have been used for years in very rough conditions without issue, its the way they are installed...like on HS stocks. The studs that failed also were not due to a bipod being mounted, it was with a sling attached. After seeing the issues with these stocks, especially on working rifles I will never use another one.
 
I has this issue on a Mcmillan stock. I used JB Weld to fill the hole re-inserted the stud and never had any issues again. It would be nice if the stud was more of a bolt on design with a flat bolt/washer on the inside of the stock and the threaded stud on the outside sandwiching the stock.
 
I tried the epoxy in mine, no go. I will be fixing a rail, just going to decide if its an anshutz or a picatinny. My rifle doesn't recoil very heavily after all the 16lbs, and being braked tames it to .223 ish levels and likely sees less abuse then many out there, never had issues with cheap plastic stocks they came with or wood stocks happening after 900+ rounds, let alone the 300rds mark. The steel in aluminum thing makes sense to me, just was wondering if it was common or if I was getting all the lemons......
 
Although we see these issues, not sure which ones you are concerned with.

if the stud shears off, then get a stronger stud. uncle mikes tend to be better. Chinese stuff tend to be soft/weak.

Stock insert pulling out and/or moving thus cracking FG shell. Only real solution is to take out the insert, hog out the foam, fill with epoxy steel and reinsert. The material around the stud is simply too soft to hold the bending load.

Best solution is to put in a nice wide pillar and use a stud that has a nut and washer on the inside of the forend. Same principle as how you fix the action bolt interface - pillar bedding.

This is why we do not have a way for the MPOD to mount to a swivel stud. simply too weak. We instead use a rail bolted at 2 locations. Even though each location isn't all that strong (doesn't need to be). having two distributes the load and that makes the set up very durable.

Swivel studs were never designed to do any more then help you keep a rifle on your shoulder. Sometimes reinforcement is necessary.

Good to know, I was thinking the rail may be the way to go here though, more specifically, the Anschutz rail. I think just spreading the load over a broad area will be great and it looks nice when completed in my opinion, or is there a down side to this that you can see?
 
I hogged mine out with a drill, filled the hole with JB weld, coated the stud in shoe polish and jammed it in. Then I let it cure for a few days, threaded the stud out, and then back in, and haven't had any problems since. Slapped a bit of paint on it and you can't even tell.
 
When I ordered my Rempel bipod I asked Henry to send me a couple of bipod studs to use with attaching the bipod plate.

He sent these great bipod studs which I believe he machines himself. The top section is knurled for added grip/bonding surface. I drilled out my A5 with a smaller bit for the tail of the stud and a larger one for the head and installed these with epoxy. I don't think anything would be able to break these loose.

Here's a crude drawing:
