malkiserow Posted November 22, 2014 Report Share Posted November 22, 2014 Does anyone know where I can get a new gas piston spring for a Browning Maxus? Mine broke today whilst out roughshooting so I had to cycle it manually. The spring is now in 4 parts so it went with a good pop! For some reason, the manual says 'do not remove the spring' but mine needs replacing. Does anyone keep them on the shelf? and is this a common problem?

Westley Posted November 22, 2014 Report Share Posted November 22, 2014 Contact BWM on Monday, if possible get the part number from them. They probably will not deal direct with you, but should send the part to your local Browning agent, for you to collect or get fitted.

jimmyb79 Posted November 22, 2014 Report Share Posted November 22, 2014 I recall a thread quite a while ago which suggested a company who were producing better quality springs for the Maxus. Might be worth some googling! Quote Link to comment Share on other sites More sharing options...
Loki Posted November 22, 2014 Report Share Posted November 22, 2014 Hi Pretty sure I noted Nordic Components or similar awhile back for (aftermarket) replacement when this problem arose with others Maxus's. Might be worth a search on here, SD or tinternet..........mine yet to fail but you never know......... Cheers L Quote Link to comment Share on other sites More sharing options...
malkiserow Posted November 23, 2014 Author Report Share Posted November 23, 2014 I recall a thread quite a while ago which suggested a company who were producing better quality springs for the Maxus. Might be worth some googling! Good suggestion but not found a company still operating as yet. I could not see Nordic had one....but an interesting company.

Loki Posted November 24, 2014 Report Share Posted November 24, 2014 Hi Perhaps you will post who you find does replacements - for those of us whose Maxus is yet to cause an issue please? Drilling around in Google there are US companies that are providers but want the gas piston assembly sent to them for about 200US - might be worth seeing what you make of it? Others US side replace some otherway...... L Quote Link to comment Share on other sites More sharing options...
figgy Posted November 24, 2014 Report Share Posted November 24, 2014 Trouble with the upgraded custom parts is the gun will only then cycle heavy loads. You can't buy just the spring it's the full valve replacement, its the reason people get annoyed as its not cheap. Try the American sites.

I do love the Maxus as a really good all round gun...... Quote Link to comment Share on other sites More sharing options...
figgy Posted November 24, 2014 Report Share Posted November 24, 2014 Seems some places will sell just the springs. I'd try getting browning to replace it for free as they should last,Best of luck. Figgy Quote Link to comment Share on other sites More sharing options...
longgun Posted November 25, 2014 Report Share Posted November 25, 2014 I googled and found this, https://www.gunpartscorp.com/Manufacturers/Browning-33164/Shotguns-35562/Maxus-40789.htm?page=4 part key:75 International Orders: https://www.gunpartscorp.com/Foreign-Orders.htm I'm sure that you can find an equipped gunsmith around. Also I have seen a homemade tool to change that spring. A long bolt, a couple nuts and washers A really very simple tool. Unfortunatly can not remember the link or key words. Anyway, I mean consider it done. Quote Link to comment Share on other sites More sharing options...

Jaymo Posted November 25, 2014 Report Share Posted November 25, 2014 they dont ship to the uk... tried and failed with them for ES100 parts last year. for some reason we are on their prohibited countries list.... It says the spring is out of stock? Plus a surcharge of $35 I actually would like a couple of items so maybe a combined order? Oh, im in a Country not on their Banned List :-) Quote Link to comment Share on other sites More sharing options...

A short fat coil spring that can break into 4 !!!!! Quote Link to comment Share on other sites More sharing options...
Guest cookoff013 Posted November 25, 2014 Report Share Posted November 25, 2014 Yep a big one. You can get a sealed piston too. If you don't shoot big loads it may be the answer. I hear browning fattened up the spring so it can take more abuse. Quote Link to comment Share on other sites More sharing options...
Underdog Posted November 25, 2014 Report Share Posted November 25, 2014 Why not just measure its diameter, wire thickness and length? Lot of springs available. Its not rocket science fellers! U. Quote Link to comment Share on other sites More sharing options...

I hear browning fattened up the spring so it can take more abuse. mine is (was) the newer brown spring... i thought this was the beefed up version but seems it either isn't or the newer version is also brittle. I have only put 70mm shells through it and up to 35gram loads. Nothing big. Why not just measure its diameter, wire thickness and length? Lot of springs available. Its not rocket science fellers! U. If someone can tell me the length that is a top idea Quote Link to comment Share on other sites More sharing options...
Underdog Posted November 25, 2014 Report Share Posted November 25, 2014 Buy it long and trim till its right! :-) Just what does this spring do ? U. Quote Link to comment Share on other sites More sharing options...
figgy Posted November 25, 2014 Report Share Posted November 25, 2014 The compression rating of the spring is important too. I'd also look to spring suppliers in the UK, you could get a few for the price of one off Browning. Is the Winchester one any cheaper? They both use the same spring.
