Works but fits loosely - KIDD Innovative Design LR Bolt Buffer For Ruger 10/22

I used this in an all KIDD build, it works so far (after about 200 rounds) but fits very loosely in the KIDD receiver. My other Ruger 10/22 has a solid polymer buffer that stays in place when the receiver is removed from the stock, where as this KIDD buffer tends to fall out easily, but works fine in use. Your call.
