Robbie's Review of HERA Arms AR15 Side Folding Unit Adaptor
I have used Hera’s SFU on several builds over the years. From chassis bolt guns to custom shotgun builds, the SFU is built like a tank. I’ve had no problems with it coming loose or rotating. If you’re looking for a way to fold a non functional buffer tube system, this is by far the best option. They are becoming harder to find in stock, but Optics Planet came through again.
Pros:
- Well built, good craftsmanship
Cons:
- None
Best Used for:
- Any non functioning buffer tube
Would Recommend:
Yes
