5 of 5 Keep it Colt October 2, 2022
Reviewer: John from Montana  
ArmsUnlimited is my go-to for Colt parts. Working on an M4 clone I needed the Milspec Colt 4 position receiver extension. Armsunlimited was out of stock so I signed up for a notification.. Within days I get a notification in my email that the item was in stock . I ordered  it immediately along with a Colt castle nut (had an endplate) and I had it within a few days. All in all, I have used these guys a number of times and it’s always a fair price (no gouging), fast shipping, and all the rest that goes along with great service.
