I bought a Well MB03 almost two years ago and I have been using it off and on (a bit more off with covid) ever since. A friend recommended upgrading it with this kit:

Power Up Kit for WELL / BRAVO VSR-10 BAR-10 MB03 MB07 Series Airsoft Sniper Rifle, Accessories & Parts, Sniper Rifle Parts, Shop by Model, VSR-10 - Evike.com Airsoft Superstore

This got the rifle shooting at 540 fps on 0.20g BBs, but as one might predict the stock trigger failed (in my case it was the spring guide stopper). I managed to pull one out of a donor rifle and it has fixed the problem for a while, but it is beginning to fail again. First of all, what does the spring guide stopper do? I cannot figure out why this would cause a slam fire.

Beyond that I am looking for a solution to this problem and see a few options:

1. Replace the piston guide stopper. It would be wise to replace both sears with proper steel ones. Steel sears seem easy enough to find, is there a clear recommendation on any of them? PDI? PPS? SHS? I finally managed to find a (probably) quality spring guide stopper from Laylax:

Laylax PSS10 VSR 10 Guide Stopper (airsoftgi.com)

Here are some cheaper options that would have to be replaced every now and then:

PPS CNC VSR-10 trigger spring guide stopper - Online Airsoft Retail & Wholesale Worldwide Shipping (moaitoys.com)

WELL Replacement Spring Guide Bar for MB4411D Airsoft Sniper Rifles, Accessories & Parts, Sniper Rifle Parts, Shop by Model, APS-2 / Type 96 - Evike.com Airsoft Superstore (not sure if this is VSR-compatible)

Any thoughts on these parts? This repair would cost as low as $6 for a cheap replacement and as high as $100 if replacing all three parts with quality brands. I have not spotted any wear on the sears yet so these could be done later.

2. Replace the entire trigger box. This will work for another few months before needing to be replaced again. Would cost around $20. No good reason to do this over just the spring guide stopper except part availability.

3. Upgrade the trigger box with a 90 degree trigger. This seems to be the most recommended option, but will easily be the most expensive at $120 to $210. If anyone is selling one I would definitely be interested

I may post a wanted ad later...

4. Something I have not thought of. You do not know what you do not know until you know it.

Additionally, I am also thinking of replacing the cylinder since the front of mine is becoming deformed. I hear that the stock piston on the Well MB03 is out of spec, will a VSR-10 one fit the MB03 receiver? Is there anything else on the MB03 that is out of spec?

Thank you for the input!

Thanks for the reply Plazmaburn! The explanation makes complete sense, thank you for clarifying that. Is there a guide for shimming the stopper? I would like to do that so I can keep playing for the next few weeks until upgrade/replacement parts arrive.

I'd say get the Laylax spring guide stopper and some SHS or PPS sears, and an Angel Custom cylinder, piston, and cylinder head down the road.
Their cylinders and pistons are pretty good judging from the ones I own plus being super cheap, so I'd definitely recommend them.

Edit: the Laylax one looks like it kind of sucks, get the PPS one as it looks way better, is in stock, and is really cheap.

did you find something negative about the Laylax stopper? Can you send me a link? Also the PPS one I sent is out of stock, will the Evike one work? Thanks!

90° or nothing

Just watched your most recent VSR build and the TDC mod vid, fantastic stuff! Is there a particular cylinder I should get? I am leaning towards the 90 degree trigger and I do not want to modify the piston to fit the well cylinder (which is beginning to deform and is in need of replacing anyways).

Thanks Plamaburn! I'll try shimming today or tomorrow to hold me for the next couple weekends

Should hold you until you kill your sears and replace your trigger unit. Stoppers do not usually break unless they are made of junk, and are piss poorly casted. Or you do something dumb.

As for trigger units, I would go with the S-trigger from Springer Custom Works. Its the best trigger unit I have used to date. (Arguable.) The bull trigger is nice, I didnt care for it. Same with the AA. While normally I am a large fan of PDI, their latest gen trigger is an abomination. Who ever thought of releasing that thing was a smart idea should commit seppuku. Its really that bad. Their older models were great, not that one.

Cylinders, AA, Maple Leaf, Lambda, PDI, Edgi, are all solid choices. I did not like the AA all that much, I kind of think I got a funky one, or my expectations are too high.

Have you tried the AirsoftPro trigger? I have heard good things about it. He also sells a decently priced cylinder:

Never used the ASPro stuff.

On hopup units, I like the Archwick Chamber better then the AA chamber. Slightly cheaper overall compared to the AA and its additional bits that are needed for it. Wrote a review of it. Archwick VSR Chamber review | Airsoft Sniper Forum

The PDI chamber and its clones are not great compared to AA and Archwick. (and some other chambers)

Thanks for the recommendation! What else is needed for the AA hop?

It's a good trigger and cylinder set.
The issue is that the cylinder has a smaller diameter than regular cylinders, but it doesn't really affect anything.
You might have to sand down the glide rings on your piston though.
Airsoftpro makes good products for vsr10s, however, avoid their hopup units and springs.
The springs are bad and the hopup unit is a PDI clone which makes it a pain in the a**e.

Thank you for the advice! The listing says the piston and cylinder are designed to go together, so hopefully no sanding XD

Do you happen to have the actual piston diameter? Is it the same as the Well piston diameter?

I'd suggest these parts.
As for the spring guide stopper, the PPS one just looks better than the Laylax.
The WELL one should work as well.

My piston is working great at 4J as it's my rifle that I never play with.

Since I did buy used I had to make a new spring guide stopper, and the piston was missing the old style piston head, but I just lathed off the knob and put some Loctite on the threads.
I would say that it's a bit better than AA and the ones similar to AA as the O-ring is what seems to be a polyurethane one which is super wear resistant and seals better for high speed things.
I'd personally put in an X-ring, but it really doesn't matter as that's going to be the last thing on your list.
I did however put some AEG shims where they fit, and the sproing and snap sound dropped a little.

Looking at Evike the AC combo is $168, the AirsoftPro (is this abbreviated AP here?) is also $168. Is there a clear winner here? I am looking around on here about buying a second hand trigger and cylinder too (AA is mostly what I’ve seen). Thanks for all help!

Sorry I’m late to reply. A lot of people chimed it with good help. I like Edgi cylinders. Overkill for airsoft but that’s how I build my airsoft sniper rifles. Way overkill, way too much time and money invested. The AA twisted cylinder is nice, and AA cylinders come as a set with the head. I also stand by airsoft pro. However AirsoftPro is a slightly smaller diameter cylinder. I know an airsoft pro piston can fit a standard cylinder if you swap o rings to make it seal. But idk about vice versa. Typical rule of thumb is match brands and you shouldn’t have sealing nor fitment issues. Key word is shouldn’t. Anyway the airsoft pro v4 kit is amazing. I wish I never sold mine. Get the cylinder and head and you’re all set. Cheaper and better than the same parts in action army in my opinion. Only problem is. Airsoft pro kits are usually out of stock. In stock? Jump on them. They sell the 90° trigger as a stand alone too. Which I think is THEE ultimate bang for your buck 90° solid af trigger.

Thank BlindSniper! I am going to keep an ear open here to see if I can get a 90 deg trigger second hand, but if not then the moment AirsoftPro triggers come back in stock I'll pick one up along with their cylinder for compatibility.
