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

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. "

Hey guys,
I'm back from about a year long holiday, and now back in america from Korea! Looking forward to being more active on this forum.

I just got one of these literally 2 hours ago. I'm kind of let down with how light and "plasticky" and hollow it feels. Given what I understand about inertia and airsoft sniping, the more we can eliminate the shock of the piston slamming home and rattling the gun (aka making the gun more sturdy) the more accurate we'll be. (Someone correct me if I'm wrong on this one.)

That being said, I went and just threw in a bunch of scrap metal/sealant into the pistol grip, and I was planning on hitting the handrest next. Do you guys have any recommendations on what to use to fill the handrest? I can't put metal bb's in there because it's too small of an opening... Sand? I've been thinking maybe metal shavings mixed into my sealant.

Also, what other upgrades to the overall feel of the gun have people performed? I've read about the wax treatment for the barrel and you better believe I'm gonna do it once I get a tbb for the gun. Can we fit a metal buffer tube on to where the stock mounts?

Thanks for all the future answers!

I'm glad you both are back! Now I have two ASR EXPERTS to help with my questions! :-D
Thanks bobgen!

Also, I'm investigating slapping a tbb in there, searched a bunch, but I keep having the same question: To install a TBB, do I first need to install the PDI hop chamber, and then add an AEG barrel? Can I simply use a asr specific tbb?

thanks :)

EDIT: And your gun is more than 7 lbs?? I just checked mine, and it's only like 4, loaded and with a scope! I don't have the bipod though, maybe that contributes to the lack of heavyness?
hmmm.... really? in all my searching, all I came across was this barrel on many sites:

is it really a 6.03, even though it says it's a 6.01?

Thanks again
Hmmm I can definitely do that, thanks Ronin.

Also, as an update, I took some old 4mm metal bb gun bb's and superglued them to the inside of the foreguard, and the results are awesome. everything feels way more solid now, and it didn't add too much overall weight to the gun. I totally recommend it!
