Mod Guide: Sentinel

After it was featured in an Episode of Can it Take a K26 there were many requests for this blaster so here it is. This is the full mod guide and overview of my Sentinel. I am very pleased with it.

Chris cartaya has a sort of walk through of his modded sentinel where it's turned up about as high as any sentinel can shoot, that would definitely be an interesting video to check out.

[@CaptainXavier]

Will do! Thanks!

[@beretnarf]

Beautiful looking sentinel! You could almost fool someone into thinking that it's just the original with a paint job. Also I think I know a guy who can get you a 3D printed mag release :)

[@WalcomS7]

85...? With K26...? That uh...that don't add up....that's about stock performance.

[@benjamin8558]

WalcomS7 How are you not verified?

[@heyitsfranklynn168]

WalcomS7 my thoughts exactly. Brass it!

[@CaptainXavier]

I really need to get a stock one so I can compare. The lowest it hit was 85. The upper was 105. I used a variety of crap darts from my bin so I could simulate what scavenging conditions would be like. I really do think a Brass Breach is going to be needed to get consistent performance. I may also removed the AR. If I do I will also take out the trigger lock so I can deprime the blaster.

[@maniacalcoyote6087]

Well, it's a fairly short spring, compared to some of the black magic people have done with a K26 (Caliburn, Rainbowpump) and has only 3" of effective barrel.

[@CaptainXavier]

No, I deleted the comments. I do not tolerate trolling or flame wars in my comment section.

[@Oniwah]

Without reading other comments, my 2¢ are as follows: that's a low fps for a sentinel. I remember stock performance being in the 90 fps range. I would recommend checking out the Home Depot door spring. I shoved one in my sentinel and without any other mods I'm pulling a 110 avg fps. (But my memory is bad and I haven't nerfed in a year or so). Keep up the good work! I enjoy your you tube presence!

[@galactic9507]

YUS THANKS FOR FINALLY DOING THE MOD REVIEW Captain Xaiver :)

[@CaptainXavier]

You're welcome.

[@gustaafdehaas]

Amazing video Captain Xavier. like i comented on the K26 episode: all it needs now is a clearshot scope painted to match.

[@DJNIAPO]

nice vid! not surprised that xshot ammo hits hard. flywheel blasters don't like that kind of ammo but I have found that springer blasters do well with it.

[@M.E.O.W.clypse]

Just picked up one of these today!! bookmarking and saving this video!!

[@CaptainXavier]

Trust me, there are better tutorials than mine. :/

Dear Captain, I just received the files for the pump grip!!!! YEESSSSSS!!!!!!!!!! I hope that I'll be able to order it off 3D hubs soon.

[@ogcrestfallen]

If I ever Find one of these I definitely plan to these mods! Great vid!

[@FlappyTheSpybot]

For more potential regarding the Sentinel, Make Test Battle also did a video on the blaster. More reference material!

[@brokcen2748]

@@BrandonPowellBlasterTown apparently he did mind you asking

[@blackrat9177]

a Nerf six clip fits in the stock but not all the way so if that was fixed in with glue or something you can extend the stock really easy

[@PerfectRequiem]

I'm really starting to want one of these things now, but the only decent blaster I've come across in my area is the much smaller Reaper pistol that's still in stores.

[@CaptainXavier]

The Reaper is a decent blaster too. I like the design. The only bad part is you cannot use Drums in it unless you cut the shell.

[@CaptainXavier]

Very similar actually. The Curator is working on a K26 Snipe build. I want to build one too.

[@GPSClaymanBOSS]

small trick if you don't have white lithium grease you can use natural oils like olive oil or grape seed oil

[@KillerNoob2001]

Would you ever do a mod guide for the Buzzbee Interceptor or the Thermal Hunter?

[@StrongHammer12345]

you should put a still of the mag release at the end of the vid. that way those of us that want to can reference yours more easily if you don't take issue with it

[@hallmonitor4426]

Captain Xavier you should make a mod guide on how you made the drain blaster shotgun I would really like to know so I could make one.

[@CaptainXavier]

I did...

[@manlymouse4408]

you should do a complete mod of a dual-strike where you make the top three barrels shoot at the same time by removing the AR not sure how good it would shoot, just a suggestion because I was planning on trying this. :):)

[@sirhenners204]

You could also take off the stock and most of the barrel

[@SnoopDoggyDoge]

85-105 is a really low FPS. AR removal is very helpful on buzzbee blasters, I recommend also gluing in the the "jesus piece" on the lever that is a spacer on the screw port. I don't think adding teflon on the seal helps because it doesn't do anything [1]. The mag release can be used as a lever format, push it forward. There are many different 3D printed parts in existence for the sentinel with aluminum parts on the way. I have taken my VGS [3] in 20F conditions with constant rapid fire, granted in pump action format. My FPS is about 100-120 FPS with an AR removed depending on the dart type. I use USCs so the FPS is lower but more consistency. All I have is is another spring with the stock one. I highly recommend NOT using a K26, especially as you are not gaining any performance currently. It MIGHT be because of the long faux barrel but I think the Air restrictor is definitely not doing you a favor.

[@SnoopDoggyDoge]

To note, I also do not think Brassing is the most effective way to use a sentinel, you can fully optimize one but at that point it's illegal from most superstock wars (cap being 120 FPS) You can get to 120 FPS pretty easily with a second spring added and AR removed.

[@acestar9122]

Hey captain X you should check out the doomlands negotiator!!

[@paranoidminecrafter]

there are some 3d printed new mag release versions

[@jacobjohnfaxholt3064]

A rough cut with removed AR's so it fires all 8 dart at one shot ( 4 half pull and 4 more at full pull og the trigger) And a spring upgrade on top of it all. Not practical at all but i think it could be a fun project

[@Flygonial]

Probably will result in stripped gears.

[@nerfmastery1012]

You should make more mag releases and put them on etsy

[@rzrider683]

Okay, I don't know how you would do it, why you would do it, or anything involving your mental health while doing it, but I was thinking about the longshot and thought" could you make it modular?" I mean, the plunger tube is extremely large, and I think it could be done, I just don't know if the fact that it is mag fed will be an issue.

[@thejeepthemyththelegend]

silicon grease is better for seals and o rings and white lithium grease is more for smooth operation like for trigger and catche mech

[@CaptainXavier]

Good to know! Thanks!

[@minecraftchickenpooh6291]

would it be possible for a commission to make a slingfire look like a model 1887 and a spring upgrade

Same here, except I woke up later than you.

[@orcatwar9810]

can you do a mod for a sentinel that looks like the rifle from the darkwatch video game

[@hunterdelta1585]

How do you find the metal handle? Some consider it uncomfortable, and one of the first Evan B Nerf vids I watched showed him dipping it into liquid plastic, adding only a little bit of mass but a more ergonomic texture. Every time I look at the Sentinel I think it has potential to be made more Winchester-esque. An in-line style loading tube, perhaps? There is more room below the breech than above, but if someone sorted out a spring assisted shotgun-style tube loader, it could be done... I remember seeing you discussing ideas with the gentleman who made the pump action, ejecting shell shotgun over on Nerf Modders Welcome (I believe). Your discussion smelled of two evil geniuses, and I think he mentioned he had ideas for the Sentinel. I hope to see either you or him perfect something. Would a non mag fed Sentinel be very practical? Nope, not at all... but the cool factor would be pretty damn high IMO.

[@dustyvancekatzenberger]

Super cool, dude.

[@osmacar5331]

if I was on the engineering course at college I wpuld be able to make you metal internals, heck I could get the metal needed and go "hey John, can you lathe and mill, or whatever it is to these chunks of metal to look like these parts please?" and probably would get that task done cause I asked nicely

[@CaptainXavier]

That would be AWESOME! Email me if you have no already! (getting behind on emails again...sorry if my reply ends up delayed...)

[@osmacar5331]

Captain Xavier​ the issue is that I may not be able to get the materials on the cheap, or I may be denied access to the lathes and what not Edit: does not mean am not gonna try, or that I only have my college for lathe access, also my main email I will send you ^^

[@CaptainXavier]

[@PhoenixFyre]

Is this a better alternative to the slingfire? I prefer lever action to most others (big fan of Western firearms) but the slingfire seems to be a bit rare and very temperamental and the scravenger is just ......no.

[@CaptainXavier]

It is superior in every possible way

[@PhoenixFyre]

@@CaptainXavier thank you for your input. Now I just have to find one.

[@CaptainXavier]

That is the tricky part.

[@PhoenixFyre]

Found a slingfire for $25 nib. Guess I'll have to use it lol.

[@joeysegg9485]

@Captain Xavier how did you get the slingfire stock so flush with the sentinel? How did you attach it?

[@CaptainXavier]

It just fit that way. And it is attached with screws.

[@joeysegg9485]

@@CaptainXavier that's so weird maybe it's because of where I cut the stock but mine doesn't fit over the end of the sentinel. Edit: It looks like you have cut yours down a little bit more than mine, it looks like if I were to cut 3 quarters of an inch more off it would fit inside. I'm glad I could use your video to help with modding this awesome blaster, thanks for doing what you do I really appreciate it.

[@WeiJunOuyang]

I have a question... would that length of k26 that you are using (i counted 13 coils) be less powerful than a k26 installed with 19 coils but half compressed? And is it normal to have a very heavy trigger pull after installing a k26 spring? I have no problems priming my sentinel but getting it to fire is a real pain. the trigger seems stuck on several occasions...im thinking the k26 might be exerting so much pressure on the catch that the trigger is unable to release it. Whats your opinion?

[@CaptainXavier]

I do not know enough about spring coefficients to answer that. And yes, I have seen catch mechanisms get stuck under the force of k26.

[@WeiJunOuyang]

Captain Xavier thanks for the reply...i might try lubricating the catch so it will be easier to release but if the situation doesnt improve i will try cutting down the spring or just stick with the stock spring.

[@muddy_armadillo]

Is that knife acid etched? It looks a little darker.

[@Sonoma1992]

Does anyone know where I can find a sentinel. I can't find anyone selling one.

[@JohnJames.]

Nice truck, I found a bundle many towns over , with over 20 blasters. I saw the sentinel, and a sledgefire , infunus with drum , so many more. 40 cdn sold, and im putting a box together for a buddy at work , for 20 .

[@aeternumthrowaway5402]

Hey X, do you use Candid? It's a very useful platform where you can talk to fellow nerfers via the nerf group. The community is rather large and we all love to show off our work on said platform, if you get the time, check it out!

[@gabecollins5585]

Is that spring inside default or a upgraded spring? If so which spring is it I might think of getting a sentinel for my first modding platform sometime but I have no experience modding anything I have never even opened a nerf blaster or anything like that before also I think with a adapter you can put half dart magazines in it

[@CaptainXavier]

I believe it still have k26 spring in it. It is a great platform to start with. The trick is going to be finding one.

[@spacemusketeer]

nice mod, wish that i could get a sentinel but i'm from the land down under

[@meroastisruined3039]

Same here:(

[@EDSKaR]

x-shot darts are lighter than most other darts, hence the increased initial velocity. This probably gives you *worse* performance because the lighter darts wont fly as well.

[@Flygonial]

More mass does not always equal more precision. Good weight distribution and sectional density, on the other hand...

[@EDSKaR]

You say this, but in my experience, the yellow x-shot darts are the least accurate and have the least range of any dart I've ever tried.

[@Flygonial]

And I cannot speak for X-shot darts as I have no experience with them. But I stand by my point that lighter darts are not inherently less precise and heavier darts are not inherently more precise.

[@HaloscornX]

what egsectly does a catch spring do

[@CaptainXavier]

Haloscornxyz it applies pressure to the catch so it catches the plunger rod when you prime the blaster.

[@HaloscornX]

O okay thank you

[@s_damen]

But does it flip

[@BryanWasHere89]

Nice. Does the lever still hurt? I know you painted it, but doesn't look like anything else was done to it.

[@optimoosejones9493]

how much force is required to prime a blaster that has a k26

[@madeline4082]

14kg in a direct prime blaster. The sentinel has a lever action system that makes it easier to prime.

[@CaptainXavier]

It depends on the length. K26 is rated a 3.88 lbs/in

[@thenerfbeaver6482]

I would love to have a sentinel, but its not $20, its $40 on Amazon Prime, or its just online? And the slingfire is $20 on Amazon, would it be worth it to buy the sentinel or a slingfire with a kit with it.
