Another member’s recent post has got me wondering what my HK 53 is worth. It’s a sear ready, all German SBR with an A3 stock. Conversation was done by S&H sometime in the ‘80s. I’m not looking to sell, just wondering is all

Dunno, I would have thought closer to 9K

To me the biggest factor would be the barrel, carrier, cocking tube/support assembly, hand guard, and rear sights of your 53. Most smiths converted the original HK93 parts to fit into a 53 size, because actual HK 53 parts were difficult to source back in the 80's. The 53 cocking tube is welded into a thicker tubing where the rear notch is on an actual 53, as that notch is over the front trunnion. The 53 has a shorter recoil spring assembly, as the recoil tubing on the carrier is shorter on a 53 carrier than a 33/93 carrier. In many of the 53 conversions, an MP5 hand guard was used. The 53 hand guard is longer because the rifle trunnion is longer than the pistol caliber trunnion.

But by far the biggest factor would be the barrel twist rate. A HK53 barrel would be 1/7 twist. The HK93 barrel is 1/12. An 8.3 inch 1/12 twist barrel would not be able to stabilize even a 55 grain bullet because the barrel is too short. So a converted 93 barrel would tend to key hole. And it is a small detail but the 53 had a long four prong flash hider. With a standard bird cage flash hider even in daylight, the fireball from such a short 8.3" 5.56X45 barrel would be big and bright, obscuring the target.

Other than the key holing issue, these are small details. But for collector value details matter. To me a 93 receiver built into a 53 using a 53 parts set by a name smith would be the high end of the market value mentioned. A chopped up 93 would be around the low end of the market value listed. So how was your 53 made? How many of the 53 details does it have? Was it made with a 53 parts set or modified 93 parts?

It certainly is close. It is missing the four prong extended flash hider and doesn't mention the rear sight but is a Terry Dyer built gun. I personally wouldn't trust Sidearm Sam's. I bought a MP5K front end from him. When I received it, the top of the front trunnion and the back of the cocking tube was cut with the torch during demil. I asked for my money back because of the undisclosed damage. I shipped it back. Never heard back. He claimed he didn't get it but, USPS said it was delivered. I didn't have signature required. He claimed he never got it. I will never do business with him again. YMMV.

A&S is mostly correct. Some early real HK53 barrels were 1/12 twist. TSC told me that they ran into some years ago for a collector who has sold off his collection at this point. The collector sold those parts off and didn't use them for his guns.
