Echo 1 ASR Knowledge Compendium

62184 Views 88 Replies 33 Participants Last post by  Sage2000
First off I'd like to attribute this information to bobgengeskahn, Ronin055, and the many other helpful people on here and on None of this is my own work; I just happen to have read about the Echo 1 ASR for 30 hours so far this week.

What I found is the lack of an "all you can eat" collection of information for this rifle. My goal is to provide that. Moderators, please feel free to edit this post.

ECHO 1 ASR - - $100-115 USD

About the base rifle:
The Echo 1 ASR is a rebrand of the WELL MB06. On the lower end of the price range for sniper rifle platforms, it is generally accepted that upgrades are required to field this weapon in a war. This is also one of the few bolt action sniper rifles (BASR) that can be easily modified to a left-handed rifle.

Are there common issues?:
The number one reported issue is a loose stock. This can be corrected by disassembling the receiver and tightening the stock from the inside.

What parts should I upgrade?:
Here is a list of upgrade parts, based on a mash-up of bob's, Ronin's, and various posts I have found. I'm adding in 'options' so you can play with your price range. When it comes to quality though, you get what you pay for.

Compatibility explained by bob:
"Cylinder, trigger, piston, spring, guide etc. are APS2. Hop up, barrel, spacers, outer barrel threads are L96."
Upgrade Kits: $33-
Echo 1 - This kit comes with "an upgraded metal spring guide, upgraded metal piston, an upgraded spring, and a torque absorbing bearing set." - $33

Angel Custom Advanced Precision Airsoft APS / APS2 / Type 96 / M99 500 FPS SP150 Tune Up Kit - $48
Includes Carbon Steel SP150 high power irregular pitch power-up spring, 100% T6 Aluminum High Performance Piston, 100% T6 Aluminum High Performance Spring Guide with guide rod.
Inner Barrel: $35-74
What to look for? Steel and brass are superior materials than aluminum.
Prometheus 455mm / 6.03mm EG Tight Bore Barrel for Airsoft AEG (AK47, AK47S Length) - $74

New Version Mad Bull Airsoft Black Python 6.03mm tight Bore Inner AEG Barrel. (455mm) - $30


MadBull Ver. 2 Precision Inner Barrel for M16 (509mm) - $35

Why nothing longer?
vindi says: "It has long been accepted in the spring powered bolt action world that anything over 509mm is pointless and actually causes the rifle to be less accurate"
Barrel Spacers: $18-20
You can also make your own if you are on a budget.
Hop Up Chamber: $85
Hop Up Bucking: $5-16
Spring: $15-20
Angel Custom PSS2 Mega-Up APS / Type96 Power Up Spring - SP150 (420~520 FPS) - $15

FF PSS2 M150 (thick type) - $18

Angel Custom PSS2 Mega-Up APS / Type96 Power Up Spring - SP170 (480~550 FPS) - $15

FF PSS2 M170 (thick type) - $20

Why nothing more powerful (>170)?:
bobgengeskahn says: "I would also recommend that people NOT put anything over a M150 or M170 spring. I have a M210 in mine and have successfully torqued/bent my bolt handle."
Scope: $45-70
Tactical 3-9x40 Rubber Scope (Ruby Lens) W/ Scope Ring Set by NC Star / AIM - $45

Leapers 5th Gen 3-9x50 AO Mil-Dot Rifle Scope with R/G Reticle, 1" Tube - $70
Silencer/Barrel Extension: $23-60 (OPTIONAL)
ELEMENT silencer "NATO" engraved 14mm +/- - $23

Echo1 M28 Type Airsoft Force Recon Barrel Extension - (14mm Negative / Covers up 180mm of outer barrel) - $55

Madbull Gemtech Quick Detatch Mock Supressor Barrel Extension w/ QD Flashhider. (Black) - $60
What DIY upgrades should I perform?:
Should I "swiss-cheese" my piston?
vindicareassassin replies: "For all those of you who are thinkin 'Oh, I'll Swiss cheese my piston as it will be lighter and spring forward easier', stop it! Leave such mods to the go faster full auto queens, for a DMR it is a good thing to have the extra weight. You will need the extra weight in the piston to help to shift the heavy weight BBs you should be using, as nothing gets things moving like a heavy object with some inertia behind it. "

Input please!
Spring of your choice



Echo 1 upgrade kit?

Also, is the "Angel Custom PSS2 Power Accuracy Piston Head for APS Type 96 Series Airsoft Sniper Rifles" worth it? Or can the same thing be accomplished with teflon?

Why are the barrels listed 6.01s? They're not as accurate as larger bore barrels of the same quality.
Thanks, I'm removing the 6.01s!
Can anyone confirm if the HP Enhanced Hop up unit for MB-01 series - will work?
Thanks bob! Updating now.

Edit: bob, I removed the 'wall of text' from your nub how-to, and inserted the link you gave. If you wouldn't mind writing up a thread tutorial for the nub you made, I'll swap out the link to yours.

Ronin, input on the Echo 1 upgrade kit? Thanks!

AirsoftExtreme: PSS96 Barrel Spacer....
Make your own!!
I was going to purchase one to 'size' my customs off of. You're right though, I should save that money for more BBs!

I wouldn't spend that much on a scope for airsoft, especially an NcStar scope. I got mine at Big5 for ~$35 and it works fine... you can check it out when we meet up.
That's how much this scope is ;) $50 is from the Angel Custom upgrade kit
I met bobgengeskahn at Airsoft Extreme today. He brought his ASR and I got to play with it. Phew is a 210 spring hard to handle! I was definitely impressed by the weight.. more of the body is metal than I thought.

They were having a black friday sale, so I picked up a Promi 455m 6.03 for $45. Stoked!
Madbull makes both 6.03s and 6.01s
If you don't like the pistol grip, try something like this:
I'd recommend bringing the ASR to your local airsoft/gun shop and fitting the stocks before you buy. The buffer tube (what the stock mounts to) is not the standard AR tube.
Ronin used the Echo 1 Kit and liked it.

If you order the PDI hopup kit, make sure to buy a nice AEG barrel too.
No one has reported trigger assembly failure from using the Echo 1 Upgrade Kit. I don't know of anyone that currently has the Angel Customs Kit installed to vouch for that one.
I've heard mixed reviews between the two. I chose the 455mm to add a functioning (permanent to be legal) silencer should I desire.
Longer barrels usually give you higher FPS, until the volume of the barrel is too much for the cylinder volume to handle, and you get a drop in FPS.
