Screws worked as described. Fit snug.

An agency needed 20 Holosun EPS sights direct mounted to Springfield Echelons. The full-size EPS does not come with the required M4 size screws. The screws provided by Freedom Gorilla worked perfectly. I was a little leery about ordering at first because I had never heard of the company, but Steve at Freedom Gorilla provided outstanding customer service and went the extra mile to make sure I had exactly what I needed.

Springfield Echelon K Series - 407K/507K/EPS/EPS Carry Screw Set - Set of 4 (Please Read Description)

This is exactly what I needed! I actually ordered the wrong item at first but I sent an email and within just a few minutes the wrong order was cancelled without any hassle. The customer service was great! I will order from here again.

Do it. Do it now!

Fast shipping and the exact length I needed when I purchased a second-hand holosun. Thank you Freedom Gorilla, you guys f*ck!
