Review for
Spikes Tactical ST Micro Rifle Gas Block
I am writing to provide feedback on a recent product I purchased. I am a fan of your products and typically do not leave negative reviews, but I wanted to make you aware of an issue I experienced.
The item is the gas tube (part number: 2A8-RGT-STMELGTB-SUGT0M1). During installation, the fit into the gas block was extremely tight and required significant force. Once inserted, the included roll pin did not fit into the slot. Fortunately, I had a spare gas block roll pin that worked.
This may simply be an issue with a specific manufacturing lot. Despite this experience, I still value your brand and plan to continue purchasing Spike products in the future, but I wanted to share this so your team is aware.

M4 Flat Top Upper from Spike Tactical

Spikes Tactical M4 Flat Top Upper
I wanted to share my feedback on the upper receiver. This is my second upper receiver from Spikes Tactical, and it is a very good product. I used mostly Spikes Tactical parts for both my 16" build and my .300BLK, and I would highly recommend this product to anyone building their own AR-15.
I also wanted to pass along a helpful tip for future buyers, rather than a complaint. The barrel fits very tightly into the upper receiver, so it may require a bit of extra force and patience to ensure it fully engages in the keyed slot. It fits a bit tighter than shown in online videos, but it works great once installed. I'm happy with my purchased and will continued to buy their products.
