Finally in stock to boost your power, range and accuracy!
For a long time we have been personally waiting for this part to complete our upgrade! The ASG - SSG 69 Precision Inner Barrel (Click Here to buy now). You may have seen our previous blog posts on upgrading the ASG - SSG 69, if not then click the links below:
Why are we doing this?
So, the standard barrels are quite poor. But for a sub £90 sniper rifle you can't expect alot. Out of the box these rifles shoot very well and in our of our previous blog posts we have listed some the upgrades we have carried out, but here is a full list of current upgrades:
# High powered spring
# Weighted piston
# Inner barrel spaces
# AEG barrel chopped to fit to standard hop unit
Below you can see the rifles current FPS with the above listed work:
Since doing these updates, we went a little too far with the AEG inner barrel and then found out ASG actually provided a purpose made SSG69 Precision Inner Barrel. So what do we expect to get from this upgrade?
# An FPS increase as you can only go so far with a spring upgrade on stock sears, spring guide and other cylinder components
# Tighter grouping down range
On top of fitting the upgraded tight-bore, we are also installing a fresh hop-up rubber for peace of mind.
First things first:
Upon opening the packaging we noticed this is a standard looking brass barrel and could do with a clean before initial use. Why? From storage the oils used in production have settled a little but collected dust and super small dirt, so give it a quick clean before assembly! Below is a photo of what you can expect upon receiving your item:
This barrel is a definite upgrade over the super cheap lightweight standard silver one. It wasn't even silver, a mucky grey. Once again what do you really expect for a sub £90 sniper rifle? This upgraded barrel also has the perfect cut outs for this one of a king hop-up unit so we expect everything to line up perfectly unlike our "bodged" efforts before of the AEG chopped up goodness...
Below shows the clean pre-cuts for aligning the barrel upon assembly:
Prepare to shave...:
One thing we have encountered is the new tight-bore precision inner barrel is slightly wider than a standard inner barrel. Today was our first time we have had to do this as usually it is a drop in barrel, but we have to do some shaving of the walls on the inside of the hop-up unit as circled below. We knew we had to do this because the hop unit wouldn't fully close tight upon re-assembly.
The first image shows a before and the last an after, we simply used a dremel to take away the edges:
Another little mod we did was slightly share the hop-up rubber guiding line slightly for an easier drop into the hop-up unit. There are no photos of this, as once you re-build you unit you will know straight away what we mean.
Excellent! The results are shown below:
# Cut up AEG barrel = 130mps / 426fps
# ASG - SSG 69 Precision Inner barrel 6.03 x 465mm = 164mps / 538
The above results were with a 0.20g BB, we of course need to do a final test with the ammo we intend to use to avoid creep issues. From a quick test, we were hot still with a 0.43g BB, we we now need to cut the spring to compensate.

We need to reduce the FPS minutely and then go testing down range! We will produce a short video and create a future blog on this soon 🙂
