Blue Bomber Wednesday, January 7th, 2009
Period of
Product Use:
6 months
Paintball
Experience:
2 years
Similar
Products Used:
Tippmann 98 Custom w/ A.C.T.
Marker Setup: ICD Lasoya Promaster: CP 14" 2-Piece, Guerilla Air 68/4500, the egg

Tippmann 98c: Proto 12" 1-Piece, cyclone, polished internals, sawed off foregrip
Recommended
Upgrades:
-New Barrel ( J&J Ceramic or Lapco Bigshot )

-Different barrel seating ( personally, I would switch the spyder adapter for one that was either cocker or 98c thread. That way you won't have to get a whole 'nother barrel.)
Strengths: -Low price
-Durability
-A5 cross-compatible
-simplistic design
-easily upgraded to electro
-no exposed parts
Weaknesses: -Quality
-central bolt spring tends to bend during re-assembly
-blow back design
Review: I have a unique perspective on this product:
I didn't buy it, I won it as a prize at Black River's "Valor vs Venom" Big Game. Therefore, I don't see the US5 in the same critical light as I see a marker that I spent money on.

My Personal Peeves (doesn't really matter)
The first feature I enjoyed when I took it out of the box was how similar it looked to the more expensive A5. However, when I got around to dissassembling the marker I found plenty of differences and oddities. For one, the ASA that the bottomline would normally fit into, that is attached directly to the valve, does not sit snugly between the two screws on either side. Apart from that mis-fitting I enjoyed how there was a monstrous buffer o-ring behind the bolt, which is at least three times the size of the 98c's. This can assist in quieting down the marker, but with the blowback design and high operating pressure there isn't any chance of it being as quiet as some higher end electros.

------------------------------------------------------------
-----------------------------------------------------------
The Good:


The Us5 has a frontal cocking knob which allows the bolt area to be sealed. With the 98c the bolt area is exposed which allows dirt, dust and paint to pass directly onto the actual bolt and it's o-ring. Without the all of the dirt entering the bolt you don't have to clean it nearly as often.

The US5 has a barrel adapter that can be switched out for an A5 barrel adapter. In this way you can change the barrel threading without having to worry about the awkward portion of barrel space that other barrel adapters can create. I am going to try and get one that is threaded for the 98c so I can share barrels between the 98 and US5

The US5's endcap can easily be removed and replaced with an A5 compatible stock.

The internals are user friendly during disassembly:
-The trigger assembly is self contained
-The power tube and valve come out easily
-The feedneck latch has it's spring mounted in the feed arm instead of the mainbody
-The only part that you really need to worry about is the frontal detent

The mechanical version of the US5 can easily be upgraded to the electro version

------------------------------------------------------------
-----------------------------------------------------------
The Bad:


Since the US5 is a an un-regulated mechanical marker it will obviously be plenty inconsistent

The US5 is unassisted blowback so there isn't much potential for upgrading speed past single trigger semi-auto, even with the electro upgrade.

Dissassembly could be slightly easier, only slightly though

The velocity is controlled by a bolt that just pokes out in front of the valve. Once that air reaches the ball it can be in a variety of speeds after colliding with the velocity bolt. In my opinion this is the worst feature of the setup. It's almost like the Tippmann engineers ran out of ideas right before they finished the design.
Conclusion: I reccomend this gun ONLY as a starter marker. As a low end mech I give it a 9 out of 10. For a low end electro I'd give it an 7 out of 10. THAT ONLY APPLIES IN THOSE CLASSES. If I had to compare it to anything in either of the two High-Class sections The grade would drop to about a 2 or 3.

For the price, the US5 is one of the best choices as a mech starter gun. Unfortunately, you'd probably be better off going for a cheap spyder or a piranha e-force, simply because they're faster, lighter and smaller.
