Pyrocoyote Posted September 23, 2020 Report Share Posted September 23, 2020 What is the difference between a HK 33a3 and a 53a3 ? They both look just a like. Quote Link to comment Share on other sites More sharing options...
x50plt Posted September 23, 2020 Report Share Posted September 23, 2020 The main difference is the barrel length. HK53a3 8.3" HK33A3 13.1 Quote Link to comment Share on other sites More sharing options...
PTRS-14.5 Posted September 24, 2020 Report Share Posted September 24, 2020 Well not really... the early HK33's had the buffer in the carrier that hit the rear strike plate on the butt stock.. Don't mix them up... PTRS Charlie Quote Link to comment Share on other sites More sharing options...
Pyrocoyote Posted September 24, 2020 Author Report Share Posted September 24, 2020 Mine must be early because the buffer is in the bolt carrier but I have also got the rubber buffer in the rear of stock. Have not give any problems yet?? Quote Link to comment Share on other sites More sharing options...
