These Polish 5.45&5.56 80% receiver blanks are 100% made in Poland using original Polish Radom Military tooling and parts. This is the closest you can get to an original military receiver! These 80 percent receivers already have both the rails and center support fully installed, and they are fully heat-treated with a black oxide finish. Polish selctor markings are pre-stamped.
These are considered 80% complete so they do not require a FFL dealer since they are missing the axis pin and safety selector lever hole. We sell the AK-Builder blank drilling fixture to complete the last remaining holes.
These are 1.0 mm and work with all the AK 5.56/5.45 parts kits we sell on the website!
**NOTE: Some minor fitting/filing may be required depending on your kit. The magwell is sized to accomidate both 5.45 and 5.56 mags, but once the trunnion is in place you may need to do some additional filing on the magwell. We have found that occasionally 1-2mm of material might need to be filed towards the rear, if you are unable to insert mags after installing the trunnion.
We are not shipping these to NJ currently due to their ban on 80% receivers.
Good receiver. I doesn’t have the full auto lower rail like the Childers receiver.
well made, material used is military grade, matte black anodized finish is excellent, Polish selector markings (no notches), center support installed, spot welds perfect, XY dimples on right spots, worth the money.
Only suggestion I have is sell/provide a hole locator to finish the receiver. I made my own from an old flat that has the holes in place
These receivers are straight and appear to be very high quality. The bends and pressings are crisp and clean. Folks in that part of the world have been making receivers like this for a very long time and it shows in the product.
COATING LOOKS REAL GOOD ALSO
Very nice 80% AK receiver
Really good work, coating is nice.
Awesome receivers, made well and work like a charm.
Bought two, both had heat treating, rails spot welded in, center trunion support riveted. Fit & finish very nice, complemented a Romy SAR-1 parts kit I had laying around making a fine fit & finished product!
