Wegalaxy Posted September 2 Share Posted September 2 Hello, I recently put a 21mm by 3mm acrylic disc on my torch for use in CQB. It cracked after taking a BB. But still held up. I am struggling to find a polycarbonet discs at 21mm as I feel it would be stronger to replace it. Does anyone have any links? Thanks Link to comment Share on other sites More sharing options...
B4by_Dr1v3r Posted September 2 Share Posted September 2 (edited) Hey there! https://www.ebay.co.uk/itm/283588380472 One of these could work, 20mm wide, at least 3mm thick - you use large heat shrink to keep it on, then trim that to clean it up. Here are some examples, including one torch! Edited September 2 by B4by_Dr1v3r Spelling Cannonfodder 1 Link to comment Share on other sites More sharing options...
Jacob Wright Posted September 2 Share Posted September 2 Really useful thread - I'm waiting on delivery of an ACOG which I want to stick a piece of acrylic or lexan on 👍🏼 hadn't even thought of eBay! Link to comment Share on other sites More sharing options...
Cannonfodder Posted September 2 Share Posted September 2 A very useful thread. Most of the places I've found either want a minimum order of way more than I would ever need or won't go smaller than 100mm Link to comment Share on other sites More sharing options...

Here are some examples, including one torch! That ebay link is for perspex and not polycarb, perspex is about as strong as the acrylic that he's broke. I've been using 6mm acrylic as can cut that myself but polycarb is a right pain as its an awkard material to laser cut as it absorbs the laser so you need a special laser source or you can use a CNC router to cut out the discs, I can make you some 6mm thick acrylic discs not had one break yet but don't think anyones been lucky enough to hit them yet. Other than that their is the kill flash as above that works well if you can find the honeycomb in the right size and strength. Link to comment Share on other sites More sharing options...

Ah, apologies, this is true - I've known people to use thick perspex/acrylic too like you say - still a great source of disks Edited September 2 by B4by_Dr1v3r Typo Link to comment Share on other sites More sharing options...
