Must have item
Review by happy owner

This is great quality, all aluminum. I had to sand the rim a little to chamber it in my HK clone flare gun.

Works great in the polish surplus flare gun! I little sanding and it fits like a glove!

As others say, requires grinding it down to hat my polish flare gun to close with it in it. Not a deal breaker. Save your expensive 26.5 mm flares and use 12 gauge, saves money and gives you options.
Good to have
Review by Alex

These are a good value and good to have on hand. It's harder to find and more expensive to acquire 26.5mm flares compared to 12 gauge marine flares. Depending on what country made your flare gun, and the model, you will have to do some sanding for it to fit. Not a big deal to do.

The only complaint I have is that the description omits that this product needs to be modified for many common flare guns. I still would have bought it, but a heads up would have been nice.
Great but need to sand
Review by Sammy
Verified Buyer
Great item much cheaper than the 26.5mm flares but you need to sand down the adapter to fit 99% of flare guns after that works great. Buy it now
Excellent quality conversion for military flare guns!

Purchased this for a Czech vz.44 flare gun - item worked flawlessly after filing around the rim of the insert (the part the extractor grabs needs to be reduced by just a hair to work with my flare gun).

A lot of customers mention the filing - what I haven't seen anyone mention yet is the instructions that come with the insert that explain why the filing is necessary. Apparently, the GECO flare guns coming out of Germany are built to slightly different specs than the Warsaw pact flare guns that are floating around. Instead of designing a different insert, the manufacturer included instructions about how to modify the insert to fit different flare guns. The filing is not difficult - if you've got sandpaper handy you can take care of it while watching your favorite TV show.

Ultimately, this is a pretty indispensable accessory if you've got a 26.5mm flare gun, especially if you plan to use it as an emergency distress signal.

Needed to do some filing for it to fit into my Polish flare gun but is well built and does its job.
Worked well after modification

Got one of these for my Polish flare gun. It fit well, but I had to file down a section in order to close the flare gun.

This is an awesome accessory for anyone with a 26.5 mm flare gun, 12 gauge flares work flawless and is a lot cheaper to use.
