I have a chiappa 22lr upper for sale or trade. This started out as a 16" m4 clone upper. I had the barrel cut down and threaded to 4.5" and put on a cheapo 7" handguard. It has no dust cover. There is a gap between the handguard and reciever due to the barrel not being built to milspec. Might be able to correct it I don't know. This was put together for a suppressor host. The barrel ends way inside the handguard so a suppressor or a fake can would be needed to safely fire it. I got a cmmg setup so this just sits in the safe. Less than 100 rds put through it. $150 obo or trade for equal value ar parts, ammo in 9mm 5.56, optics knives. Located in west linn.
