|When I bought this, I didn't have high expectations of it being of great quality. MAN WAS I WRONG!!!!! These [when I say these, I purchased both the 22lr model AND the 410/45 model] are meticulously machined, polished and then appears to be coated with some type of oxide finish. They are VERY smooth with no sharp corners or burs, and they fit my 1980's era Polish 26.5mm flare gun PERFECTLY.
I also had a Polish flare gun case, sold here also, and the adapters are kept in two flare spots inside the case along side the gun itself.
Don't hesitate to purchase one or both of these adapters as they are well worth the money spent should they be needed in an emergency.|
