Lloyd90 Posted April 24, 2015 Report Share Posted April 24, 2015 Hello gents. Have gone to swap the sling attachments on my 22lr BRNO for a bipod stud that can also attach a sling to. I bought the studs before hand and have just taken out the old ones to see that the screw threads are very different. At first try I haven't been able to screw them in, although I didn't want to push too hard for fear of damaging the wood work. Any advice here guys ? Will attach a photo to help Quote Link to comment Share on other sites More sharing options...
saddler Posted April 24, 2015 Report Share Posted April 24, 2015 With mine I dismantled the factory ones (removed the swivel part) and filed the remaining stem until they were a close match to the sling swivels I wanted to fit. Quote Link to comment Share on other sites More sharing options...
steve_b_wales Posted April 24, 2015 Report Share Posted April 24, 2015 On one of my rifles, I drilled a small pilot hole in the wood, which was just smaller than the thread, and then used Araldite on the stud's thread before screwing it into the stock.

Lloyd90 Posted April 24, 2015 Author Report Share Posted April 24, 2015 I haven't a clue what any one you just said Sorry lads. The big ones on the left were already in the rifle stock, so there's a hole that I'd like to get the smaller ones to fit into. The rifle stock is a standard wooden BRNO no 2 stock Quote Link to comment Share on other sites More sharing options...
Olliesims Posted April 24, 2015 Report Share Posted April 24, 2015 (edited) The original sling studs have a wood screw on them, the new bipod studs you have bought have a screw designed to go into a nut, so unless you remove the stock, drill out the hole and put a bolt set into the stock I don't think you will be able to attach them? I maybe wrong Edited April 24, 2015 by Olliesims Quote Link to comment Share on other sites More sharing options...
wymberley Posted April 24, 2015 Report Share Posted April 24, 2015 That's a very coarse thread for the fore-end nut version. You'd be hard pushed, I think, to get a nut of the required diameter with a thread like that. I'd be inclined to install the new ones, carefully adjusting the hole size if things get too tight. Once fitted, as Steve said, remove and wipe with Araldite and refit. Quote Link to comment Share on other sites More sharing options...

The rifle stock is a standard wooden BRNO no 2 stock Araldite can be mixed to a thick consistency, and used to fill in the 'gap' when installing the new studs.

Cheers for explaining lads, sorry for not following. ATM there isn't really a 'gap' as the new ones aren't screwing in with there being space, they're not going in at all. The screw doesn't seem to be 'biting' if you get me. So even If I filled with Araldite it would be too tight. Steve, did you drill out yours a bit, fill with araldite and then push it in ? wiping off any excess ? Just going to google what Araldite is lol Quote Link to comment Share on other sites More sharing options...

Just going to google what Araldite is lol Not quite sure what you're saying but looking at the photo's the root diameter of the new stud is greater than the original and therefore the hole will need widening if that is, indeed, the case. You would need Rapid Araldite available from most hardware stores. I have to say that as that thread is so very coarse it is for use in wood but a different design from the original.

welshwarrior Posted April 24, 2015 Report Share Posted April 24, 2015 In short you've bought the wrong type. You need swivels to fit into wood not a machine thread (a metal nut) Quote Link to comment Share on other sites More sharing options...
Good shot? Posted April 24, 2015 Report Share Posted April 24, 2015 (edited) These should be what you need, with some Araldite Rapid set glue. Edited April 25, 2015 by Good shot? Quote Link to comment Share on other sites More sharing options...
Lloyd90 Posted April 24, 2015 Author Report Share Posted April 24, 2015 These should be what you need, with some Araldite Raped set glue. Would they just screw straight in ? I'll have a look from my computer, hopefully available from the company I bought mine and they'll let me swap them. Cheers lads Quote Link to comment Share on other sites More sharing options...

Just going to google what Araldite is lol As the holes in my stock were smaller than the stud screws, I just opened it up a bit, then smeared Araldite around the threads before screwing into the stock. You could drill holes the same size, or a mm bigger than the screws, and apply Araladite before inserting into the stock. Quote Link to comment Share on other sites More sharing options...
activeviii Posted April 25, 2015 Report Share Posted April 25, 2015 Look for uncle mikes sling and swivel set for wood. Comes with the two wood studs, short one for front of stock. If hole is to big then wood glue and lightly hammer in a couple of make sticks. Let glue dry, trim sticks down the knife being carful not to cause damage. Drill fresh small hole in the same area as the match plugs and then screw in new studs. The one you have look like the m4 machine thread studs. I use the one long machine thread on the front but I cutma hole for a nut to glue on inside of stock. Quote Link to comment Share on other sites More sharing options...
