bradders Posted January 19, 2016 Report Share Posted January 19, 2016 One of those infuriating things for many when buying a muzzle brake etc is correct timing. With the ARs for example, a common practise is to use a crush or peel washer. The peel washer is more satisfactory though for many reasons. As with many of these things, they are usually only available from America, and is very few sizes. Seeing as I use a lot of these, I felt it time I had some made here in the UK (one more self sufficient item for the UK market) To start off with I have gone for 2 of my most popular sizes, 1/2" and 5/8" Both are .750"od and have IDs of .505" and .630" respectively. Material is A2 Stainless. As you can see from the pic they are made up of a series of laminated shims, each .002" thick and come as supplied with a total thickness of .040", so will cover at least 1 complete revolution of any thread pitch. This means that the layman can now purchase and fit his own muzzle devices without having to revert to a smith for lathe timing All you have to do it catch the edge with a knife and peel off the layers Depending on application and demand I can get other sizes made.

Deeredriver Posted January 19, 2016 Report Share Posted January 19, 2016 Well done, great idea. I tried to find some a couple of years ago without success. I'm sure peel washers to fit M18 threads would be useful. Link to comment Share on other sites More sharing options...
garyw Posted January 19, 2016 Report Share Posted January 19, 2016 Bradders-please explain to me[and a few others] who are slightly ignorant when it comes to the working of a brake-the technical side-and the timing of one- thanks Gary Link to comment Share on other sites More sharing options...
johnnyb0_1 Posted January 20, 2016 Report Share Posted January 20, 2016 Hi Mark, As posted above, great idea for correcting timing without resorting to very expensive machining time/ set up. Time to get my Mitutoyos out and see what sizes I need… Just how fine/thin can you peel them down to without shagging them?? Cheers. JP. Link to comment Share on other sites More sharing options...

Andrew Posted January 20, 2016 Report Share Posted January 20, 2016 I have made many of these bushings for other people but when it came time to install a brake on my rifle I bought a self indexing brake to avoid the lathe time. What a joy. I'm surprised more people don't make them.~Andrew Link to comment Share on other sites More sharing options...
MJR Posted January 20, 2016 Report Share Posted January 20, 2016 Are these washers any good for adjusting the play out of bipod legs? Link to comment Share on other sites More sharing options...
The Gun Pimp Posted January 20, 2016 Report Share Posted January 20, 2016 Very useful Mark - but I'm usually looking at a 0.75in internal diameter. Are these available from stock? Link to comment Share on other sites More sharing options...

Vince, As I'm sure you can imagine there are so many variables with internal and external diameters that it's hard to plan this out. These are the first ones and I have already had a couple of enquiries for M18. I can have them made in any diameters and thicknesses in laminates of .002", but would need to know quantities. Manufacture is around 1 month Mark Link to comment Share on other sites More sharing options...
Swarovski1 Posted January 20, 2016 Report Share Posted January 20, 2016 I would imagine these washers will be popular.i will put my 6.5 cal 18/1m armalon brake up for sell now. Link to comment Share on other sites More sharing options...
brown dog Posted January 20, 2016 Report Share Posted January 20, 2016 I'd be saying 18x1 too. (what happens to these when you repetitively take a brake off to swap over for a suppressor and back again?) Link to comment Share on other sites More sharing options...
bradders Posted January 20, 2016 Author Report Share Posted January 20, 2016 I'd be saying 18x1 too. (what happens to these when you repetitively take a brake off to swap over for a suppressor and back again?) There ones I always used were aluminium (or aluminium according to the Yanks) and they don't wear as such. These are A2 stainless so tougher, and I don't see any issues, or delaminating problems. If any problems were to occur then you get the Bradders guarantee.....I'll replace them :-) As for M18, what OD would we be looking at? Link to comment Share on other sites More sharing options...
