Q
Enrique Tachias, member, from NM, United States, asked on February 19, 2024

Is the muzzle pinned welded? I hope not because I want to run a suppressor.

Manufacturer Answer
A
Answered by Spikes Tactical, Manufacturer from FL, United States, on July 23, 2025

We recommend that you call us directly with the part number to ensure that you get the correct model. But if in the description it’s not stated pined, it should not be.

What length is the hand guard I wish to replace it with a OD green?

Expert Answer
A
Answered by Ethan, Gear Expert, from IL, United States, on August 01, 2022

The Spikes Tactical Carbine Cold Hammer Forged 11.5in Upper Receiver uses carbine length handguards. Any 2-piece drop in carbine length handguards that fit via a delta ring and handguard cap will fit this upper.
