The Hackbolt is a combination between the U-Bolt Vanguard and the Hellfire.

There are two versions: The Hackbolt, a plain version just like the U-Bolt and the Hackbolt STEPN'T which is for those who prefer meme lowers. Of course, STEP files are included should you decide to add your own graphics.

Contains updated versions of the Hellfire's pivot pin plates that are compatible with both the Hellfire and the Hackbolt.

The main benefits are that:

1. It is universally compatible. The U-Bolt Vanguard is not compatible with my hand-guard nor a small selection of others, but this is.

2. The design of the Hellfire's front plates should hold up better than the U-Bolt simply due to print orientation.

3. Should the plates fail, they are easily and quickly replaced, unlike the U-Bolt.

4. More color customization.

UPDATE 4-17-2021:

• Revised mag well to now have tighter tolerances. Should eliminate the slight mag rotation that was occurring. Tested with Gen3 PMAGS. They still drop free. If yours don't, then take a file/sand paper to the front of the mag well interior.

• Switched over to a low shelf to accommodate more room for Skittles.
