Super fast delivery and I mean super fast. Regulator much better than my original
A J W PRESCOTT

“ Thaw large plenum has arrived and been tuned for my Condor .22....It is not for... „ more just 250 onward as advertised. This Regulator returns the peak performance of your un-regulated gun with the advantages of a regulator. Mine is now tuned at 150bar for the Hades .22 producing a very consistent 40fpe. up to the Exact Jumbo Monster 25gr producing a consistent 47fpe all with just a simple change to the Hammer tension Power Wheel. If you wish to just shoot the heavier 25-30gr pellets or slugs setting the regulator to 170-180 Bar would be advised to attain approx 925fps (50fpe). My Condor .22 is now performing as I had always dreamed it would. I have never been happier and recommend to all....Fantastic job PCPTunes. „

“ Regulator delivered quickly but at a price. The unit itself appears well-made and durable, unlike... „ more the original one fitted to the RM8. The best feature is the shot consistency of power/pressure which is the main reason I ordered it due to the Walther Rotex version being quite poor in this respect. Fewer shots per fill is noticeable due no doubt to the rifle's increased power. I now have a rifle that is consistent within its power band which inspires confidence resulting in much improved accuracy. Overall I'm please with my purchase and would recommend this to anyone who is currently not sure. „
Ralf

“ The Regulator was delivered within only 3 days from Mumbai to Germany. The assembly was... „ more easy and fast. The change in power impessive. 3 thumbs up for the team and the regulator. If I ever need to change the O-rings, I´ll contact you. „

Robert from AZ

“ Got my high flow valve and angled tank adapter today and just finished installing it.... „ more Fast shipping, and that angled adapter is nice. Much easier to aim and hold steady. Gave it the 3500 pound test out back with a 2x4. 43 grain went clean threw and into the tree with a 10/13 setting. Also got the parts to fix my factory valve with the high flow valve. 95 hammer and back to the factory spring. Valve didn't like that heavy spring, broke the bushing in half and the bushing spring looked drunk. Learned some things messing with these valves. „

Dom

“ This is absolutely fantastic. So many more shots per fill and extremely consisitent. Like all... „ more the stuff here, it is very well made and does what it says. It could be improved by adding a filling valve dust cover to it but I guess this would put the cost up. They could add a cheap rubber one but then I guess many people would swap it for their custom one. I would anyway as they are so much better and will last a lifetime, unlike the cheap rubber ones. Anyway, this product completely transforms airforce airguns. „

“ Just received my 1250 cyclinder with fill probe today. Arrived in good condition here in... „ more the states. I like the idea of using the fill probe instead of removing the cylinder to charge. The cylinder I received is made out of aluminum by the pressure gauge is red from 200 bar to 300 bar. I am a bit leary of charging this thing to 300 bar as stated in the description. „

“ Nicely made but DOESN'T FIT the latest FX Bobcat MK2. You will need a... „ more MaleToMale Adapter to attach to the shroud. It would be really helpful if this was documented more explicitly on this site.

“ I required custom size of this cap 28 x 1 for Cometa Lynx V10 MK2's... „ more shroud.The product came 3 days after it was sent (sales team continuously notified me about the progress of producing the item). Firstly when I received the product it was very light and very good packed. When I opened it up it was very nicely stored in various soft materials and even plastic bag. The product was awesome quality, anodized, very nice made and fitted my shroud perfectly. I would happily recommend this product to every one. I would also recommend this store/business for any sort of production of metal elements. Exceptional service! „

John

“ I could not be happier with this product. After reading the reviews of the competitors... „ more probe and its poor construction I was weary to find one that would be a good replacement for my Career 707. Ell when I first unpacked this probe I was completely blown away. Any worry I might have had was gone instantly. The construction is very high quality and that was apparent from the first handling and the fit into the probe opening is spot on! I have used this fill probe for over about a six week period and it has performed flawlessly. I highly recommend it to anyone looking to upgrade an aging probe or who might be looking for a fill probe to replace a missing or lost one. Excellent service both before and after the sale made for a complete experience that was a perfect 10. I WILL do more business from here again. Thank you for such a great product. „

“ Amazing kit that, when combined with the rest of the components advised by the PCP... „ more Tunes team, gives your Condor power enough to turn it into another kind of air gun.

“ I bought this valve, I had converted my condor to .257 and have been... „ more shooting 74 grain slugs at what I thought was powerful, until I installed this valve, my 74 grain bullets became not accurate and just blazed to the target, they were moving way to fast. I upsized to a 89 grain bullet and this thing drives them faster than my old valve did the 74 grain, accuracy is great I get 8 good shots, cant give you velocities since my chronograph hasn't arrived yet. But I do know it will push these 89 grain bullets through 2x4's at 100 yards for 8 shots straight. „
Tomasz

“ Quality product. Much better than original stem. Shipping was very fast to Europe. Great communications... „ more as always. „
Joel Jimmerson

“ In this review I will speak only to the build, finish, and quality of the... „ more parts and to my experience with PCPTunes. I received this valve as a part of the package with the 1 liter 4500# bottle. The quality of the valve was superb but it did not fit exactly for my specific requirement. This was not the error of PCPTunes but rather my own error. My first thought was that I was stuck with a product that I couldn't use. One email and a very quick response later my problem was solved. I cannot express just how much of a relief it was to have the level of support that I received from the Sales Team. The response, the solution, and the replacement was fast. When doing any business over the internet, the great unknown is trust. As far as these guys go, you will get a superior product at a competitive price and they stand behind what they offer. I will post a follow-up review once I've had time to quantify results. „
Tomasz from Europe

Sumatra Threaded barrel UNF Extension for Shroud/Moderator

Sumatra Threaded barrel UNF Extension for Shroud/Moderator was machined for customers who wanted to use universal shrouds which had unf threads.

The Sumatra air rifle design limits the usage of common UNF shroud/moderators due to non-standard threads on the barrel.
This adapter is a solution for those seeking options who want to use quieter shrouds or moderators for a better backyard airgun shooting experience.

Made from high grade Aluminum Alloy.
Light weight
Hard Anodized to prevents scratches from rough use.
Male End has 1/2 X 20 (UNF) (To attach shroud/moderator)

Shipped along with the adapter is a "1/2 UNF Thread Protect Adapter Delrin" to ensure the UNF threads are not damaged in transit or storage.

Fits the following models of Sumatra Airguns:
Sumatra 500
