Since there is not much online for the Adaptive Armament line of rifles, I thought I would add this post.
I wanted to build a mid-range DMR and decided to use an M4 for the platform. I found the Adaptive Armament Scout rifle on closeout from a bankrupt airsoft business for $140 (reg$245) and couldn't pass it up.
The AA Scout is a well built rifle and performed perfectly right out of the box. Internals are SHS and is V2 Standard. The ambi. fire-selector is the same as what's used on VFC rifles. Further specifications can be viewed on the Adaptive Armament website.
I wanted to boost the rifles performance just a little in hopes it will out range an average AEG 'battle rifle' so I added a few modifications. I wanted to build a rifle that was a good compromise between power and reliability and in time I'll learn whether I have succeeded??? At the time of this writing the rifle has about 1000-rounds through it and is performing perfectly.
The gearbox is stock other then I shimmed it to achieve good gear lash between the bevel and the pinion. Also shimmed for gear teeth mesh, and proper side-to-side 'play'.
The stock motor is an SHS Standard High Torque 125K and on a 3-cell LiPo is more than fast enough. I do not notice any heat build-up in the grip.
I added an M125 (stock M110) irregular pitch spring, type-O (non-ported) cylinder, o-ring nozzle, Maple Leaf 'Mr. Hop' packing and Maple Leaf 'Omega' nub. The rifle 'hops' .32g BBs easily with plenty of adjustment left on the hop-up dial.
I should also mention that the 'lips' of the ML packing rubber were too long for the hop-up chamber. I had to sand the 'lips' down just a little bit to get bbs to push into the hop-up chamber from the magazine. Also, sealed the cylinder head with a couple wraps of teflon tape over the 0-ring. I trimmed excess tape so it does not extend forward of the cylinder (fitment concern).
I shimmed the inner barrel to fit perfectly in the muzzle end of the outer barrel. Also sealed the packing rubber to the barrel with Pliobond.
The rifle is very accurate and BBs fly perfectly down range with no left or right curve.
As of this writing I have not chronographed the rifle (I have a sky screen type Chrono) but will add to this thread once I get that info.
I am very pleased with the performance of the rifle. If the rifle breaks-down or anything changes I will add that info. to this post.
