Will hk 416 22 pistol accept buffer tube?

Answer 1

The HK 416 Pistol and Rifle are both the same in construction. the lowers are the same also. It is a scaled version of the HK 416/417 model (.223) only a dedicated .22 rifle. the place the Buffer-tube inserts is capped for pistol specs. But yes a buffer tube from a full length 416 .22lr should work. Be aware that by putting the Buffer-tube WITH a stock constitutes a short barrel rifle and is illegal unless you pay the ATF the $200 tax stamp and process the request to own through them.
