Keystone Overlander...Very light and compact… It’d be nice if the stock could slide forward just a bit more to sit flush against the back of the receiver. But that might breach the 26” legal limit.
The light, carbon fiber wrapped barrel, free floated “handguard”, pistol grip, and collapsible buttstock lend the Overlander an exotic look.
I replaced the excessively long pistol grip with a BCM KD 3.0 Gunfighter shorty grip. Saves over 30 grams. With the design of the receiver’ I had to lop off the beaver tail and some of the trigger guard ledge.
I’ve always looked at the Keystone Crickett single shot bolt action rifles for kids with interest. I think the Overlander can serve as a kid’s training platform AND yet continue to serve as a very light and compact backpack carbine for adults.
The buttstock storage compartment provides a good cheek weld for kids, but adults will need to do a good turkey neck cheek weld onto the extended twin rails to get low enough to see through the peep sight.
The Overlander, like the SU16c, can fire while the stock is folded or collapsed. Something that the Ruger takedown rifles can’t match.
I did experience some frustration with the collapsible stock…the stock collapses about an inch on almost every shot. Occurs when pulling the buttstock firmly into the shoulder pocket…preloaded such, the light recoil of the 22LR cartridge is just enough to collapse the stock. I suppose you could call it a recoil reducing feature, but it’s annoying.
This leads to the four step firing routine:Eject spent caseInsert fresh cartridgeClose BoltExtend stockCock hammer
Trying to resolve the issue, I used a small triangle file to cut the wire stock notches deeper and square it up toward the rear of the buttstock…allowing the forward side to retain a ramp. I also added a ⅛” preload spacer to the spring. The problem persists. It is an annoying issue that hopefully Keystone can resolve with future iterations. The spring loaded catches do have a steel roll pin insert for lockup with the wire stock.
They do offer a version of the Overlander with an AR like adjustable buttstock/buffer tube setup. This is a poor solution…ruining the weight advantage of the Overlander, hinders the rifle’s length of pull as a platform for children, and eliminates the really compact collapsed form factor….probably 5 to 6 inches longer when collapsed than the wire stock. Wire stock is far superior for a backpack carbine and worth overcoming or adapting to the lock up issues.

Osight S, from the OLight company, is a compact RMSc footprint, enclosed emitter red dot sight. It features a -proprietary “OAL” aluminum alloy housing that they compare to titanium and 7075 aluminum. The sight comes packaged with iPhone elegance..
The elegantly packaged sight is bundled with a complete screw kit that should get your sight mounted on 99% of every RMSc compatible pistol or mount out there. Very much appreciated If you ever had to track down the screws needed to mount a red dot on the Sig P365XL. If you end up choosing another sight, you just might want to order one of the Osight FN Screw Kits…available separately.
Osight S is a rechargeable red dot. That alone is pretty cool, but the sight’s most notable feature is the magnetic charging cover that when attached immediately shows the charge status of the optic. Remove the charging cover, you get the charge status of the charging cover itself. Charge the cover with the included USB-C cable and then it is then able to charge the sight 3 times. This is a very cool feature, but I’m kind of suspicious about the long term viability of the sight’s internal, non-replacable battery…just my experience with smartphones…batteries faltering after a few years.
And at my age, I worry that I’ll misplace the charging cover…so, I turned it over to my grandson to mount on his KeyStone Overlander.
The Osight S offers three reticle options….the standard single 2MOA dot, a circle, and a dot inside the circle.
The Osight S does offer the illumination auto adjust sensor which works fine when you are in the same light as the target, but when under a shaded cover shooting into bright light I had to boost the reticle a bit to see it well.
My grandson prefers the circle dot reticle, but if I were running the sight on a CCW pistol I’d probably just run the dot sans circle to extend battery life.
I found the sight a bit of a challenge to zero. Osight says that each “click” is one MOA. I’ve twice been sent to sensitivity training so It must be true, I lack sensitivity, since I could not detect a “click”...audible or tactile. There are tiny tics surrounding the elevation and windage adjustment screws. But trying to move the adjustment just a tick or two was challenging for me. Multiple times I overshot windage and elevation adjustments. Something like the Shield Sights MiniDial would be helpful.
I like the low deck height of the OSight, it is only .255” which places the optic window quite low on most pistols and allow many pistol iron sights to “co-witness” in the lower third or quarter of the sight. I was hoping it would be low enough to allow “co-witness” with the Keystone Overlander’s iron sight…not quite, with the circle dot reticle, I do see a rising sun…just barely missing the horizontal stadia. Personally, I’m not a fan of combining “back up irons” with a red dot since they tend to draw the eye away from being target focused…a problem for many shooters accustomed to iron sights trying to adopt red dots.
OSight S is available in black and olive green bodies…I think it makes sense to stick with black since you want that sight body to blur away with your focus locked on the target (with the red dot superimposed on it). Any color is tempting your eye to shift focus to the optic body.
The sight features IPX7 so it can handle immersion in a meter of water. The temperature range for operation is only 32-113 degrees F. Maybe ok for a CCW pistol, but we’ll push well beyond that backpacking the Keystone Overlander in the middle of Wyoming winter weather. We’ll see what happens.
Still, this is a great option. It’s affordable, rechargeable, versatile, and elegant.

The most popular youth rifles are the Keystone Cricket and Chipmunk. Lightweight, short length of pull, and discrete loading and cocking operations that are ideal for young shooters.
The Keystone Overlander is based on the Chipmunk action, but fitted with a carbon fiber wrapped barrel, pistol grip, and collapsible stock. More versatile than the fixed stock Crickett or Chipmunk the Overlander easily accommodates youth and adult shooters.
For new students learning gun safety, cheek weld, steady hold factors, and trigger manipulation, dealing with peep sights is needlessly complex. Mounting a magnified optic just introduces the hassle of scope eye relief and eye alignment. For beginning shooters a red dot simplifies things.
I started off trying a Primary Arms Micro Red Dot. Keystone offers a Crickettinny Rail kit, but it is excessively high. I found a low pic rail with a curved base but getting it mounted was a bit janky. The rail coupled with the picatinny mount on the red dot raised the line of sight a little too high for a proper cheek weld…especially for kids. It was ok, but not optimal so I continued my search. I decided that I needed a RMSc adapter plate so that I could mount a low, lightweight “pistol” reflex sight.
Found exactly what I was seeking at Rucker Machine. The Rucker Crickett/Chipmunk Optics Mount available in RMR or RMSc pattern. Curved bottom to mount atop the Keystone receiver using the two drilled and tapped holes just forward of the ejection port.
I had an idle Crimson Trace 1500 that was bundled with the early version of the KelTec P17 Red Dot Slide before they changed to the much better Viridian RFX11.
The Rucker mount is as thin as possible just maintaining needed depth for the optic mounting screws. I was hoping that maybe I would get lower ¼ co-witness with the irons, but the CT1500’s base is a bit too thick…possible that a more svelte sight would co-witness…maybe the RFX11 or a Shield RMSsc would get low enough.
The Rucker mount is not exactly cheap, but it is well worth it if you’re setting up a Cricket or Overlander for a young shooter.
This reflex sight setup adds very little weight to the Overlander. It also keeps the overall height of the Overlander to a minimum…especially if you’re running the AmbGun recommended BCM KD shorty grip on the little carbine.
So that’s it…Keystone Overlander, BCM KD grip, CVlife bipod, Rucker Machine optic plate, and an RMSc reflex sight…a very sweet, on target setup.

I typically don't care much for bipodsThey introduce the variable of the terrain, sand, gravel, dirt, concrete, wood, into the “steady hold factors” equationVersus a shooter's sling that insulates a bit and can provide support for not just prone, but sitting, squatting, and offhand, too.
But our 4 year old ‘lil gunfighter wanted to try a bipod for support. And parents wanted help keeping the muzzle out of the dirt and directed down range.
I Paired a CVLife QD pic rail Tactical bipod with the Keystone Overlander. A terrific combination for kids shooting prone….and adults alike.
One surprising benefit of the bipod for the Overlander is that it prevents the stock from collapsing during live fire recoil…even if forward tensioned.
Raising bipod awareness…The Tactical bipod is Great for bullpups, too, where the sling, as a shooter's aid, is less effective.
Compared to the Magpul bipod…Size and Weight basically the sameTilt is smooth on Magpul, indexed on CVlifeCVlife features numeric markings on legsCVlife can fold both to the front and to the rear…great for bullpups or backpack carbine versatilityWith legs folded, the CVlife can keep a rifle balanced upright on its adjustment knob, whereas the Magpul knob is pretty tippy…although it has really nice knurling. I do wish the bipod could splay its legs at a sideways angle to create a wider platform for kids. Our little test shooter figured it out, so maybe not worth the added complexity and weight. CVlife Tactical bipod…about half the price of Magpul offering. And with similar features.

Given the Overlander's short "handguard" there is no effective way to use a sling as a shooter's aid. As an advocate of the shooter's sling, I've never been a fan of the bipod. I generally think they introduce too much of the variation of the terrain into the steady hold factors. But I think the Overlander as well as the RDB bullpup might benefit from a lightweight bipod. Testing the CVLife.
Mission First Tactical Achro “without color” or gray man 22L BackpackFeatures an ambi access CCW pocket and the velcro MFT Multi-Mount PlatformMy P17 fits with room to spareI’m not a fan of off-body firearm carry, so I secured a Pioneer Woman paring knife. Perhaps I should include a spoon and fork, too. The subdued company logo is discreetly positioned above the exterior storage pocket where I organize my family ParaQuito insect repellent…you’re more likely to be killed by a mosquito than a Grizzly.Only opens diagonally, I wish it folded out full like the 30L model. I use the soft eyeglass pocket to carry two “camera” phones.The carry handle is sturdy and the sweat chimney helps keep you coolSturdy padded shoulder harness with adjustable sternum strap.The 2.4 pound pack is a good match for mountain bikers and day hikers.Ambi water bottle pouches can hold up to 32 ounce containersPadded compartment accommodates my inadequate, but long lived, 13” Lenovo Thinkpad. But I wish the compartment kept the notebook off the bottom. I made use of the laser cut molle to install a holster and secure a barrel condom to carry the Keystone Overlander. Rugged enough to handle bumpy mountain bike trails with grace.Not quite tall enough to comfortably accommodate our 19 ½” 10/22 takedown build, but I believe the 30L version would be tall enough.
Because gun shot trauma all require the same emergency response whether from 22LR, 9mm, or 45ACP.
