I wanted something that was compact and agile enough for CQC but having enough range, accuracy, and "omph" to still be competitive when transitioning to a field environment. I went ahead and purchased the OM-15 M8 to fill this role.
My first impressions positive. I've been a long-time user of KWA pistols and AEGs, all of which have been solidly constructed and performed flawlessly for me, so branching out to a brand I haven't encountered before made me a bit apprehensive. Needless to say the exterior construction and fit of the Oberland Arms M8 is superb, maybe even better than the quality I am used to with KWA.
Unfortunately while King Arms does an exceptional job of the exterior construction, their internals leave a lot to be desired. Within two weeks my AEG lost the ability to fire semi-automatic, a problem that I am still trying to diagnose (I have it narrowed down to either the trigger assembly, cut-off latch, or the sector gear). While a majority of other high-end AEG manufacturers have transitioned to bearings, King Arms still uses bushings with shims and they stick more than I'd like. The gears, piston, and cylinder however seem to be solidly constructed.
My biggest beef out of everything else, even the semi-auto issue, is their quality control. My M8 had so many loose hex screws and spring pins I nearly called them for an RMA. However because I am knowledgeable with working on AEG's it didn't take long to get everything re-tightened (at which point everything fit snugly together with no wobble). The screw that keeps the buffer tube on for the stick will wear down very quickly under the stress of moderate skirmishing because it is too short and doesn't screw into the lower receiver/rear of gearbox fully like most others do. I'm having to find a replacement to re-mount the stock.
Three out of five stars. Minus one star for outdated internals. Minus another for poor quality control. I would recommend this to veteran players willing to put work into the gun to make up for King Arm's shortcomings. I would recommend this to new players once King Arms squares their QA department away and gets with the times in using more modern V2 gearboxes.
Superb exterior construction and fit.
Unique, rock-solid rail system.
Shoots ~370 FPS out of the box with .20's
Flexible skirmish environment: Can do CQC or field.
Internals are out-dated and somewhat fragile; lack of bearings is disappointing.
Quality Control is very poor -- make sure to tighten all screws and spring-pins before use.
