Umraex 22 LR Colt M4 OPS w/Tactical Railing & Muzzle Compens
by Tay M Date Added: Wednesday 07 April, 2010
I bought a Colt Umarex M4 Ops to give to my son on his 18th birthday, which is on March 25th. Fortunately it arrived 1 week before his birthday allowing me the opportunity to test fire it, and I’m glad I did.

First of all the magazine kept falling out, so I supported the gun with my palm under the magazine to keep it in place. I tried shooting Federal bulk pack ammo and experienced jams about every 6th or 8th round. I fired about 100 rounds this way. I called Umarex customer service and spoke to a lady named Allison. She said she would send me a new mag catch, and suggested I try different kinds of ammo. She also told me to turn the bolt speed adjuster in 9 complete turns from flush, which I did.

The next day I tried it again (I had to wait until my son was away) with Federal bulk ammo, Winchester bulk ammo, and some CCI Mini Mag ammo. The Federal jammed at about the same rate as the previous day, the Winchester jammed about every 2nd or 3rd round, and the CCI Mini Mag ammo went about 50 rounds with only 1 jam. I called Umarex customer service again, and this time spoke to Glenn. He e-mailed me a UPS pre-paid return label, and said he would put a rush on my repair after I explained it was a birthday gift. He seemed confident that it was just a matter of tuning, and that it could be easily resolved.

I took my package to UPS late in the afternoon on Friday the 19th and then tracked it online. I figured my chances of getting it back in time for my son’s birthday were slim to none. According to UPS it arrived at Umarex on Tuesday the 23rd. I received it back via FedEx on Wednesday the 24th!

The repair order said they repaired the magazine catch and replaced the mainspring. They also gave me a detailed set of instructions for field stripping, unlike the vague ones that came with the rifle. I took the rifle out and fired one full 30 round mag of Winchesters and one full mag of Federal without a single malfunction. I fired most of the 2nd mag a fast as I could pull the trigger, and everything worked perfectly.

Was I disappointed with the rifle when I first received it? Yes. Am I pleased with it now? Absolutely.

We have put well over 700 rounds through it since getting it back from Umarex, and it now functions perfectly.

Umarex’s customer service was OUTSTANDING! Thank you Glenn, Allison and all the others at Umarex who helped me to have my rifle back in time for my son’s birthday.
