This review is specifically about the Well R4 the mechanisms and design still are suppose to be compatiable with TM parts.

The Gun Reviewed:

The Mechbox Design

Unknown, havnt opened gun up, Knight might be able to offer an opinion as he has it currently while he works to fix a problem with it (more on that later)

Outer Construction
Very small and compact, a great PDW for those who want a change from the MP5K, Sturdy gun, most of the exterior is metal, has 20mm rails at the barrel of the gun to add lasers or flashlights, and one large rail on top of the gun for a red dot or ACOG. Selecter switch is the same basic design as other H&K guns and is in easy reach of the thumb. mag released is located in by trigger guard, mags are located in the grip much like a pistol. sights are flip up sights located at front and read of the gun, flip up when stock extended, back down for use when retracted.

Metal Parts:
Most of the body, unsure of whats metal for the internals

Field Stripping:
havnt tried it, but it doesnt look easy, requires bolts to be removed with Allen key. but again, Knight may be able to give better insight on this

Field Test:
this gun supports an impressive ROF, emptying a low cap in seconds, but because of the size, it lacks severly in range. another problem is the way the stock bars are located, there is no covers on them, allowing debris to get in, jamming the stock, not allowing it to extend (Knight is trying to fix this for me).

Longevity (big word for reliability):
Can't comment yet, havnt had the gun long enough


Part Compatibility
lots of extra goodies for it internerally. also suppose to be fully compatiable with TM parts. mags come in boxs of low caps and mid caps, and as individuals.

Summary
great CQB gun or back up weapon, not recommended for ranged combat or as a primary, remember to bring lots of mags though if you do use it as a primary though, and maybe a couple extra batteries

Pros:
-Small Compact Design
-Sturdy Metal Body
-High ROF
-Affordable (Well/TSD models at least)
-Ready to go from box (comes with Battery and Charger)

Cons:
-Selector not crisp
-FPS low even with upgrades
-Exposed stock
-Need Lots of Mags and extra batteries (low MaH)
