You can improve the power by tuning it properly as Briha ,Moulindu and others have done.
A good tuning will not only improve power but smoothness and accuracy too.
But I doubt wheather or not it will reach power level of NX.

Well said Basu :D

Going a little off topic here. I am surprised how it is taken for granted that a factory product will perform upto the market standards only if it is tuned by the customers after procuring it. Do not see any reasons for us to have accept such attitude from any company. Definitely if the customers can better a product, the company can easily implement the changes and deliver a quality product in the first place. It is about time we stop encouraging sub standard products.

^^I'ld say in this gun-challenged/deprived gem of a nation, let's be thankful that atleast a handful of options exist now. Yes this statement is absolutely pathetic but please tell me is there anything that looks non-pathetic around you in public. We simply don't have the legacy of finesse, & it's not something that would arrive one fine day. Let's wait it out.

IHP35 even in stock can blast through medium hard wood planks. I guess it's about time for the person to open up his rifle unless the pellet is at fault or the wood is super hard.

Brihaji, you rightly mentioned that "tuning" broadly reffers to enhancing a product to squeeze the last bits of performance from it.

Even a Ferrari can be further tuned, that doesnt mean it doesnt work fantastically, bone stock out of the factory.

What I find funny is how it is an accepted fact that particular Indian air rifles will work at acceptable standards only after they have been tuned.

As far as demand is concerned, I believe we have the numbers. Even a small percentage of Indians equals to a sizeable number to justify quality products.
It is our inherent mentality of accepting sub standard products which encourages people to be complacent in their quality control and development.

I guess there is always a scope for performance enhancement for any AR .
Here in India , among various ARs , it is Precihole ,who started offering standard guns.
But even Precihole also can be further fine tuned .
Tuning or the process of performance enhancement will continue for springers as usual.
The point is , how early other manufacturers follow the same path.
IHP has woken up late.
Let it be late than never , so are the other manufacturers.

I can only speak about springers.

When someone says he has tuned his rifle and has improved its performance, this can only be verified by before and after measurement of parameters like accuracy, power and trigger perfomance. Unless one actually does objective before and after measurements using a Crono, the effects of tuning can be misleading.

I think the problem is compounded by the fact that Indian "untuned" springers often show a gradual improveent in performance as they are brken in and then a gradual deterioration over time. So also "tuned" rifles are great at purchase and may degrade over time, but unlese objective measurements are made, all assessments could end up being subjective.

So when it comes to the question "When to tune a rifle?". Unless one is already an expert in the business one could wait till a springer is "broken in" to see if any worthwhile peformance improvement can be gained, provided one is dissatisfied with the performance. Another good time to tune is when the rifle's performance is so degraded that you no longer enjoy shooting with it.

My personal experience is that if you simply open up a rifle fully and reassemble it - its performance changes. It could end up being worse.

Please let me know how this can be done - I need to be educated :roll: :roll: :roll:

accuracy , velocity / power , trigger settings , etc are subjective. and i would think in airguns..as with any other hobby.. this is the driving force. almost anything mechanical can be pushed to a higher level of performance provided one has the required knowledge / skills. from what i can only call a basic tune to replacement with after market parts and on to even modifications to oem parts. all to achieve a performance level ideal to the user. given the subjectivity , a tune process may start right out of the box !

its not really about a mentality of accepting substandard products BUT an acceptance of the substandard as the standard...which is universal human nature. the market decides the consumer and the product.
Throw me to the wolves....I will return leading the pack.

Well said mercury :D
Finally - If tuning achieves what you are looking for - well & good :D
But to be obsessed with "Tuning" on a perfectly smooth shooting & accurate AR is playing the "Blindman's Buff" :lol:

@brihaji, i'd vote for the preci's trigger. It is like a spot on an otherwise brilliant air rifle.

Dear Briha,
Hope you know well that process of tuning is delicate and demands intense attention part to part.
IFgian Pratik did fine tuned his PH and posted the drawing of trigger on this forum also.
It helped the gun to deliver deadly accuracy shot after shot.
I admit with Mercury when he says anything mechanical , leaves a scope for performance enhancement.
I used the word "fine tune " in case of PH and not in case of Kolkta made guns.

From my personal viewpoint the most intractable problems that are most difficult to remedy by any form of tuning have nothing to do with spring, receiver, piston or washer. Most often the issues are discovering that the most suitable pellets that group the best cannot be used because the rifle tends to shoot them too far to one side or too high or low and the rear sight cannot be adjusted to compensate for the error. or there is a degree of barrel droop, or worse barrel "rise".

A third issue is non standard barrels. Precihole barrel sizes are slightly different from IHP which are slightly different from others. My old Weihrauch use to just about take 5.6 mm Eley pellets - which were too tight for any Indian rifle (I did not have an Orion then). SDB have the narrowest barrels and GSmith are pretty much ruled out, which is sad because my SDB 65 seems to be as much or more power than the Orion, given the same pellet. Need to see if this lasts.

Factory tuning would normally remove such issues, but then again most Indian air rifles have no factory tuning.

:agree:
Additionally the 'Breech' ID differ from AR to AR.....causing problems in pellet fitment...
Add to this dimensional differences in pellet skirts cause leaks....
Improper breech seals & piston seals also contribute to the woe.....most being made of leather (till synthetic piston seals & 'O' rings have made inroads.....
May be these are reasons as to why ARs are an enigma with each one differing from the other.....
Well the show goes on :lol:
