KNS Piston + WBP Carrier Body BUNDLE

Nice quality carrier/piston combo. Used the milled bolt carrier/piston for an Arsenal 107fr34 that I didn’t want to damage the original carrier assembly. No problems with head spacing and the piston install was easy and no problems with a quick function test. As a side note, the milled carrier does not work in an arsenal Sam 7 SF. Looks like the WBP carrier will need to have the auto trip milled off to go into battery in the Sam 7. Would be nice to offer semi auto carrier options from the get go for those in the need of that but pleased otherwise!

Used the WBP bolt carrier w/ kns in an over gassed slr106 and worked perfect.

I made a 5.56 AKM using the WBP parts kit which went amazing, except for that the brass it was ejecting was being ejected over 20ft away and denting the brass. I added in this KNS piston and was able to dial it back to be normal. Now the rifle is much more pleasant to shoot too!!

Shoots better than ever!

I ended up buying 2 of these bundles since they are such a good deal. This bundle of a carrier and KNS piston saved $40 over buying them separately elsewhere. The WBP bolt carrier worked perfectly in my WBP Jack762 rifle but also in another Russian AKM that I had built from a parts kit. The KNS piston is almost a necessity if you are going to suppress an AK and I wanted a use a spare carrier for it so I wouldn't have to modify my factory carrier.
