Interesting how the lowest rated reviews are missing - now Oct 2024. Hmmm. As another reviewer in late Aug. 2024 stated, the holes in this 1913 adapter did not line up with my HK SP5K. Holes simply are not lined up on THEIR PART. Visibly off by a good bit. I contacted JMAC. They promptly referred me...

Great product

by Joe, Verified Owner from KS, United States Written on November 11, 2024
Great product and very solid, just had a little bit of work to get it into place on a Century Arms AP5 but once installed it is set in place and won't budge. If you want something thats cheap and works well then this is it.
Would recommend: Yes

Jmac sp5k adapter

by Abc, Verified Owner from WI, United States Written on August 29, 2024
Looks nice but the holes need to be adjusted. I have an hk sp5k and not a clone. The Holes did not line up. I had to grind the holes to make it fit. I should not have to do additional work to make it fit for a quality product. Don't buy if u don't have a dremel or plan on making adjustments.
Pros:
  • Looks nice
Cons:
  • Holes do not line up. Additional work is needed to make it fit.
Would recommend: No

JMAC IS SOLID GEAR

Another piece of quality made JMAC gear. I recommend it but it's not cheap. I highly recommend Optics Planet as well - OUTSTANDING product selection and service!

Nice Snug Fit !!!

by MLars, Verified Owner from UT, United States Written on November 15, 2022
I received this item along with the Jmac brace. All the components of the system were of the highest quality. This adapter was well finished and Fit very snug into the receiver so much that one the pins had to be tapped in. Some may view this as a negative but I'd rather have it that way than loose.
Pros:
  • Great Fit
Cons:
  • May not allow push pin takedown without tools.
Would recommend: Yes
