Drill a hole in the barrel. Thatll drop it.
Yeh just change the spring to a lower one.

M100 or a M90 should be enough,

I think a M100 is around 340 and a M90 310.

I'm not 100% certain but I know its about that.

you can cut the stock spring down a little.

Its a big job to replace a spring if you are completely new to working on airsoft rifles.

Zeroone would do the downgrade, fit metal bushings (better reliability) etc for around £40 i believe.

Careful with the M100 though, I bought a 105 for my LR and it came up to 376ish. DOH!!!!!!!!!!! Id just sorted the seals on it though. be dropping a 90 in in the next couple of weeks, hopefully thats more sensible.

Already comes with metal bushings, the GB on the A&K LR300 is actually really good.

I have a A&K lr 300 and I fitted it with a Systema 1J spring and it is a sexy little beast.

Shoots around 290 but has 50m range easily. I would recommend the 1J whole heartedly.

Re: Downgrading a&k lr-300 by 50fps

What fps does the 90 take it down to?

[Abbadon101]

Re: Downgrading a&k lr-300 by 50fps

It would probably be around the 300 mark but it can vary from rifle to rifle, the 1J is meant to take it to 328ish, but trust me on 290 it is an excellent gun.

cant wait for mine to come looks awsome, i didnt relise they were so powerful out of the box

If you can get it crono'ed before you downgrade it as mine was probably around the 350 mark before I downgraded but never got it crono'ed. If you have a local site (who have a workshop) get them to crono it and then if needed downgrade it and be aware that it can take up to 1000+ rounds to break it in.

Cant fault mine now, had issues with hop and bad sealing upon first purchase, one guarder cylinder set and G&P hop unit with TM hop rubber and bucking, hits 50 accurate, past that its anybodies guess really(wheres me chicken bones gone?).
Stripped the piston at one stage which removed teeth so got the Modify torque up smooth gearset(oh sweet lord its nice) then my motor failed in a ball of flames and smoke(first time Iv had Subaru style turbo flash from an AEG, thats for sure ) so replaced with a systema magnum, by god the setup is now nion perfecto, fast, with good range and accuracy. all on stock 9.6s.
