Shockwave now sells the 14″ front end kits for building Mossberg 500 and Maverick 88 non-NFA 12-gauge firearms. Mossberg part number 92514. This kit includes one each of the following:

• 13488          Tube Nut 500A/835
• 11239P         M590/835 Mag Cap Parkerized

After legally building your non-NFA 12-gauge firearm, you can then probably sell your original front end online for anywhere from $75 to $200—and recoup a significant part of your costs of upgrading to the uber-cool 14” front end.

All NFA rules apply, of course. And before building a non-NFA 12-gauge firearm, ensure your local and state laws mimic federal statutes.

Please select the $15 shipping option when you check out to avoid delays in shipping your purchase. Thank you.
