Umarex Gauntlet .25: Complete review (Video)
« on: December 27, 2018, 11:40:09 AM »
Well my friends here we are once again, as we look into the face of a familiar friend. You know the friend I am talking about, the friend that you have known for a long long time who asks for advice and never follows it, the one that asks 20 questions but only listens to 10 of your answers. The one that could so easily change just a few things and be on top of the world…. Yup……. that friend.

Today I offer my review of an old friend who went to the gym but only applied 10 of the 20 answers I gave him over a year ago. Today I run the Umarex Gauntlet in .25 Caliber through its paces. Typically I will rip a rifle apart and give you the ……..wait for it……….. inside scoop, but this time I want to review the rifle for what it does out of the box first. I will make follow up videos that offer complete tear downs and detailed information to assist a potential buyer what is under the hood.

Please remember, I do not get paid to make these videos, your comments and feedback are my compensation, please be generous!

With the thought in mind, that PA et. al., sells this PCP for $300, I would expect a a few, less-than-stellar issues with the airgun. This said, both the loose bottle and broken air stripper (really an air deflector) are inexcusable issues Umarex knew about, but failed to correct.

As a disclaimer... I have owned two Umarex airguns, neither of which met, or even came close, to expectations gained from their advertising. So am I surprised at your findings? No!

And lastly, good performance in an airgun is more than just tight groups, small velocity spreads, or factory regulators. Rather it is the overall rating, loose bottles, broken parts, etcetera, included! Enough said!

Rather good performance with only a little work.   But fitment of the valve retention screws and the loose bottle situation are troubling - especially for uninformed buyers.

Thanks for your test report.  My .22 Gauntlet also had a broken air stripper when I received it.
From your report the .25 cal. is an "interesting" rifle.  Col. Charles Askins is quoted as saying "only
accurate guns are interesting."  I am still working on refining my .22 with the updates you used.
I shot my Gauntlet so much I wore out the "O" rings on the bolt, Umarex sent replacements at no
charge!  After I get the improvements finished on the .22 Gauntlet I may have to get a .25, quite
affordable.

I have a 22 cal Gauntlet that works as well as a cheap airgun was expected to work...basically OK but with some warts. 

I read  lots of information on the gun and was expecting to replace the air stripper with a Hajimoto piece and also the moderator with Haji parts...do the drilling on the barrel cover, replace the bottle with a larger one and in time rebuild the regulator to correct specs and drill the upper gun regulator out for more air to be available.

The gun produced ≈820-850 fs with 14.35 JSB'S with the Umarex regulator/bottle well below factory specs...but I DON'T know what weight pellet they used and ≈720-750 fs with a new regulator and 22 ci bottle off ebay.

Haven't yet rebuild the regulators but have the Belleville washers/shims/oil filled gauge and other pieces and parts to build the tester on order.

TOO many other airgun/powder gun projects and run out of time because I'm a lizard...when the sun comes out so do I, when it goes behind a cloud or the weather changes I go in...weather is starting to become more cooperative and the pieces and parts are coming in...SLOWLY...slow boat from China.

I have airguns from 2 large to a buck and a half and powder rifles twice that cost and many I built from the ground up...and ALL of them had warts of some kind...NOTHING IS PERFECT...especially cheap airguns.

Accept that fact and expect to do some polishing on your toys...WHAT do you expect from 3 bucks...Filet Mignon? ;D ::)

Good Hunting.

I convinced my shooting buddy to buy a Gauntlet in .25 caliber. Using the JSB Exactas (25.39 grains), he's getting the same FPS (875) as I am out of my Cobra. The advantages I have is range, and trigger finesse (Timney Calvin Elite). When I say range, his 100 yard groups are about triple mine (≈2 inches). Part of that could be the trigger.

However, you have to give a few strokes for the simple fact that my Cobra cost 8 times more!

There you go...EVERYONE has the "compare this with that" syndrome up their noses...basically doesn't mean squat and is completely ludicrous many times.

FWIW I did an "apples to apples" comparison with my 22 "fist shoe"...Umarex 13 ci bottle/regulator with my Ebay 22 ci bottle/reg USING 14.35 gr JSB Exact K...the Umarex reg/bot produced ≈820 fs and the 22 ci reg/bot gave ≈750 fs....QUITE A DIFFERENCE...BOTH bottle were filled to 3000 psi and I used one mag and pellets from the same can...I also have a shut-off valve installed on the gun so all I had to do was swap the bottles...a <5 min task.

I anticipated doing this testing and ordered the parts to build a regulator tester and they came in yesterday...took all of 15 minutes to put together while I was having coffee.

Heavens to Mergtroy....the Ebay reg was set to 800 psi and the Umarex reg to 1100 psi...duh... :o ::)...of course I knew right away something like that was going on the moment I saw the first number from the larger bottle.  The pressure for the Umarex reg should be up around 1200-1250 and should produce close to 900 fs or a bit higher for 14.35 gr pellets.

I only shot 5 pellets each test...no need to waste air OR pellets.  The SD for the Ebay reg was also twice as high as the Umarex.

I suspected this was happening and I have shims and belleville washers ordered from McMasters to correct BOTH regulators.

NOTHING earthshaking with this observation/regulator test as it has been covered several times online including all the "stuff" you need to do to "fixit".

This rifle is plenty accurate enough as is for me to go ahead and add on the "Haji" Super tune kit maybe, but as many of you know increasing the reg psi to increase the velo can also cause the "lighter" pellet accuracy pellets to go south and you will need to increase the pellet weight to take advantage of the higher velo.

There is an OLD adage with powder guns that states energy increases at the SQUARE of the velo and increases DIRECTLY with the weight of the pellet....basically energy increases faster with velo than with pellet weight...but accuracy is NEVER found at the highest velo...usually between 5 and 10% below max velo....so far I've found that to be true with airguns.

I will post my results when I get the regs rebuild just for kicks...I'm sure similar results have been posted online somewhere.
