Review of the Elite Alpha Trooper Spring Upgrade kit from Worker.

Review of the Elite Alpha Trooper Spring Upgrade kit from Worker.

                I don’t know how long it has been out by worker, but I found worker’s spring upgrade kit for the EAT.  5 kilograms is safe for the priming rod, and doubles the spring-weight!

               

                All parts in this set have been used (minus the Vaseline), and I find all parts perform their duty adequately.

(More after the break)

                Throwing the 5 kg spring into a stock breach, I found the performance upgraded from around 60 FPS to 81 FPS!  With a brass breach, it gets even higher!

                The buffer is meant to be placed against the plunger or plunger rod, and it performs it's job well.  It is a silicone buffer pad for those interested in the specifics.

                The Vaseline, I would recommend to NOT use.  It is safe on some rubbers, but on others, it can eat away at them, being petroleum based and not silicone based.  I recommend purchasing lubricant from Out of Darts, as his is safe, and the type I use.  It is also silicon based and won't hurt your O-rings.

                Speaking of O-rings, one is included in this set.  It is a fine O-ring, smaller than the original, but I used it for a different project than my EAT.  It does work great in the other project.

                The last item included is a little catch spring...the one in the picture may not look like much, but I assure you, the one included is BEEFY.  In-fact, it can pull the bolt sled BACKWARDS, and not fire it, due to the way slam-fire is set up, and how strong the spring is!  It definitely holds the weight.

                 Now, let's look at the price...$6:34 shipped from china to the US!  Astounding!  It is well worth the money.

                

                Only gripe: Shipping time…worker takes a while as it is coming from china to Pennsylvania.

                All-in-all, I give this kit a resounding 5 out of 5.  At a wonderful price of $6.34 from China to Pennsylvania, the spring, catch, and buffer all make this set well worth it!

Sorry for the delay in posting.  It has been a month, but I hope to review a few more products from worker when they arrive, including their Retaliator plunger, catch, 7 kg spring, and bolt!  Until then, the summary:

Summary:

Pros: Great spring, Great buffer, Amazing catch spring, Price is fantastic for what it is!

Cons: Spring takes some time to arrive, but really can’t be helped.
