I was a little hesitant to order at first but I am very glad I did I received my upper receiver in about a weeks time and couldn’t be more pleased with my purchase. It fits my lower nice and tight with no play or jiggle at all. Also the assembly is top notch no dings or scratches anywhere polish job on feed ramps is really nice and the parts used are of very good quality best assembled upper I have ever purchased online. If you are building a micro ar pistol you need this!!
Only 4.75"??? Thats not practical!!!!!
Well, no it isn't, but it sure is fun. I've never met anyone who shot this and said they were bored. This is an epic little noise maker and will brighten any range day, literally. You can probably light a cigarette three lanes over from the muzzle flash alone.
Looking for extreme accuracy? This ain't the upper for you. Can you hit a IPSC sized steel target at 100 yards? Yes you can.
We build these to eat any commercially manufactured ammo you feed them. They don't care if it is high dollar US produced 5.56 NATO or the cheapest Romanian steel case you can find. It will function with all of it.
With 5.56 NATO M193 it's gassy on a carbine buffer. We'd reccoment an H2 if that's what you are shooting. If you are blasting cheap imported steel case, a standard carbine buffer will probably do well.
In reality our uppers are extremely well built with attention to detail paid to every step of the process. We use only components that we are familiar with and have been using to great sucess for years. We inspect and prep every part prior to assembly, then test fire and confirm accuracy with each unit.

We test these with commercially produced 5.56 NATO loads and recommend you use only name brand new manufacture 5.56x45 ammunition.

We will not warranty any issues arrising from the use of reloaded or commercially remanufactured ammunition.
