OG Spec Mosmatic Swiveling Gun

Pretty good, but save your money and get the Mosmatic gun IMO.

It's a pretty decent gun but I would save the money and get the mosmatic gun with the high quality mosmatic fittings (70.016 and 70.028). The swivel is a tad better in the OG spec gun but not much. The fact that the swivel is recessed in the gun on the OG looks cool but isn't really noticeable in use. The fit and finish on the normal mosmatic gun is better after owning both. The OG spec had quite a sharp edges from the molding process whereas the mosmatic gun had none. You can't go wrong with either one. The swiss made mosmatic swivels are the best I've used.

Great quality, a bit on heavy side

You get what you paid for, period. This is a great quality gun and it has a bit of weight to it. I do find myself getting a little fatigue on my had for holding it for a period of time. The trigger is not as light as some of the other cheaper gun, but it is still pretty effortless to squeeze it. Mosmatic fittings on this gun is the smoothest I have used. You do pay for the "OG" premium price but if you want best of the best and something last you a long time, this is it.

Great quality, love this gun.

Love the quality of this gun. It's not cheap but I love how it works and the fact it's got short inlet. 6 moths warranty is a bit short though. If this is top quality (certainly feels that way) why OG doesn't offer 12 months?
