David's Review of Spikes Tactical M4 Flat Top Upper

Some might argue this point but over the years I have received "junk" from some of the larger manufacturers. Now I check the bore on all uppers before I start assembling the AR. From what I see Spikes uppers come in between 0.999" - 1.000" consistently and this gives you amazing performance. Would I purchase another, absolutely!

About David from SC, United States

I am a 62-year-old male / married for 39 years. I live on the coast and love it. We are 5 minutes from the beach and 10 from the closest river. Outside sports are a part of the culture fishing, hunting, plinking or playing golf! I enjoy repairing and building my own guns and helping family members with keeping their gun of choice in top working order. My wife and I go to the range at least 3 times a month and really enjoy it. Being from the Southeast learning to use a gun is second nature and yes safety is a large part of this. I got my first BB gun at the age of 6 if memory serves. Optics Planet provides a platform that is user friendly and cost competitive. This is my second year with them, and I hope to continue well into the future. I have to mention customer service / it is second to none.
