    My pal bought a new Streamline a couple months ago.. same issues right off the bat with a leak… Sent it back to dealer and they replaced the pressure gauge.. 100% now and a fantastic unit. 

    1 tiny leak can ruin your day!

     The accuracy  sounds excellent on your BSA  so once this small leak is fixed, you're good to go!

    To determine the DOM you have to use the serial number on the gun, not the bottle. I doubt the gun is 4 years old…… Just the bottle. Furthermore, BSA doesn't make the bottles. They are outsourced. The age of the bottle does not reflect any issues in this case. 

    One of the big contributors to the difference in price is the Mk2 does not have an over-price Minnelli walnut stock with the rose wood, or Palisander wood inserts that accent the fore end and the base of the pistol grip as well as the precise laser cut chequered panels. 

    Also the regulator. The Mk2 is less efficient than the SE. No specific details other than BSA claims the SE is 11% more efficient than the Mk2.  

    And the CCS or Customer Configurable Shroud.

    I sent an email with my guns' serial number to BSA inquiring as to how to decipher it. It's my understanding through the UK's BSA forums it may take a day or two for a response. I'll update here as soon as I hear back.

    Ok gun filled to 3000 and I unscrewed the tank off and will reinstall in ten hrs….at least like Dave said find out where its leaking .

    Make sure you remove the bottle correctly. If you dont you will cause another leak by ruining the o-ring on the bottle. You have to loosen the bottle about 3/4 turn then shoot the air out of the regulator. Once the air is out of the regulator you can unscrew the bottle completely. If the reg doesnt empty within 6 – 10 shots unscrew the bottle a little more and repeat the shooting until the reg is completely empty.

    Thats a strange comment my MK 2 most definitely has the minnelli Walnut stock along with the Rose Wood Caps as does my spare stock. They must send them to the states differently configured than the U.K.

    I think Dave is referring to the discounted rifles being sold here in the USA are the black wrap stocks (or camo wrap).  Before the SE model came out we could order it with the walnut stock.  When all three stock versions of the MK2 were available (before the SE and at regular price); I believe the walnut stock was about $100 to 150 more than the wrapped stocks.

    I preemptively ordered a complete o-ring kit from the UK that is supposed to be delivered today. I'm going to try to repair the rifle myself. If I cant I'll send it in for warranty and if they give me much grief about it I'll deal with Amex and get my money back.

    Ive had a lot going on with my life since getting my r10 so I haven’t been able to shoot it more than a single magazine but so far it seems to be holding air.  Maybe I got lucky?  Thanks for starting this thread though and I hope everyone keeps it updated with their experience.  Seems like a lot of people must have bought these.

    i guess it doesn’t really matter but how do you tell when it was made?  Does the serial number show the date of manufacture?

    I asked BSA in the email I sent. They told me the DOM of my gun (2015) but did not offer my request how to decipher the serial number.

    Well I've now replaced every o-ring in the regulator block assembly and It's still leaking, regulator was all green and crusty inside. IDK, guess I'll try to send it in under warranty. I was really temped to just smash it into pieces.

    Oh man, that's a bummer.  Did you clean the fill port check valve?  That is where mine was leaking from.  It had the same crusty green crude that you found on the regulator (mine had it on the reg also).

    Yes. It was completely full of green crud as well. Like totally full. I could't get the "inside" part of the regulator out but the o-ring for the outside part was totally shot  as was the bottle o-ring, the others were honestly fine but I changed them anyway.

    Here is maybe a little motivation to give it one more try.  Quick shooting session tonight.  Dusk and mosquitoes chased me off.  10 shot group @ 50yds 15.89 JSB's using front bag.

    I actually did try again and got the regulator all the way out and cleaned it as well as I could. Still leaks though. sounds like it's coming from the actual regulator area. I just can't get this thing not to leak. I feel like a new regulator might fix it but can't really be sure. I appreciate your support though Rodeo. 

    That's about how this gun shot as well, super accurate.

    I replaced the o-ring on the regulator piston – the only moving o-ring in the reg.  When I went to take the old one off it literally cracked in half.  Definitely replace this o-ring if you have not already.   I have read nothing but good things about the Huma regs for the R10's if you decide to go that route.

    The Huma Reg is super awesome! Its very easy and fast to adjust, because you dont have to take the rifle apart. just turn the bottle 1/2 to 3/4 turns off and shot the firing valve chamber empty. now you can turn the whole regulator block to the side so that you can unscrew the reg without colliding with the rest of the gun. you dont need to remove the bottle.

    to get access to the hammer spring just unscrew the end cap (in my location it was glued because of energy level restrictions)

    The R10 is a very very nice rifle to tune and play around with. Fantastic Trigger!!

     

    It can leak out of the fill port – there is a spring, o-ring and a steelball inside of a small brass housing-part. thats the fill port valve.

    to change that o-ring you have to remove the connector part (brass) for the bottle and at least one flat head screw on the side if i remember correctly.

    I bought one of the r10s !aso, but no leaks. Look at the serial number and there will be a dash and a number after. That should be the year made. Mine says -14. So 2014 manufacture date sounds resonable. What does yours say?

    If you are speaking of the bottle, yes they have a date code of 2014. I contacted BSA with the serial number on the breech of my gun and they told me the gun was made in 2015.

    Well my new R10 MK2 I got from PA the first of July has a serial number the ends with -AB.  So based off mine who knows.  The -14 kind of made sense but my rifle throws a wrench into that.  Further more mine ends in letters, not numbers?  Even if a -14 means it was a rifle from 2014 that doesn't mean the rifle was built in 2014.  Maybe they made the action/receiver in 2014.  That doesn't mean it was assembled in 2014. I think they are using up spare parts and assembling new rifles to use up parts and get out the door to make money.  It just doesn't make sense to have a 300-1000 +/- rifles, in boxes, sitting around for 4-5 years.  My rifle showed no signs of green corrosion (I even took the reg apart) but that is the sign of brass corrosion which doesn't take long.  As for my rifle it is fine.  I have had it all apart (as I am that type of guy) and all was well, no green corrosion.  I had one leak at the buddy bottle oring but I caused that and was easily fixed (I unscrewed the bottle fully and after reading the directions it said to unscrew 1/2 turn, shoot rifle to empty reg,…., if not you will cause a leak at the buddy bottle oring.).   My rifle held air fine until I did what the directions said would cause a leak.  Since I replaced the bottle oring it has held air fine. I have two friends that bought R10 rifles from PA a week after me and have had no issues.  Niether leak and both guys told me they are tack drivers.  

    I posted all this not to reject the OP issues.  I believe him and that sucks.  I respect him for manning up and trying to correct the issue on his own.  He lost nothing but only gained in my opinion.  Now he knows how to take the rifle apart and put it back together.  What I really posted for was to say I think there is a flaw in the ending of the serial number being -14 meaning the rifle was built in 2104.  Since mine is -AB it am clueless as the what the date code might be.

    I know that PA has gotten in more than one shipment of these discounted R10's.  I was told this by a rep at PA.  Mine was from the first shipment and I had the green crud + leak.  Maybe the latter shipment(s) were newer stock?

    My R10 mk2 had the reg seize up and stop working around march. I had this R10 for a couple years but the last 6 – 8 months before the leak I didnt shoot it. When I pulled it apart the reg had the green corrosion in it. It was badvenough I just replaced it with a huma. It works better than ever. I bought it used so I dont know how old it was or if the previous owner introduced moisture with his fill equipment.
