"So, I've had this gun for a few months now and been absolutely blown away with how effective this thing is in the field. Out of the box performance is everything I was looking for out of a DMR setup. Real wood and metal give it a good heavy feel backed up with a better look. My fps readings were about 430 with .20, 400 with .25, and 360 with .30's !!! Strap on that rail for any sight or optic you prefer. I personally went with an AIM reflex red dot and basically...if I can see it, I can hit it! On top of that the head turning I receive is pretty awesome, it really stands out.
Real wood & metal, sturdy design
Higher fps for range and accuracy with heavier bbs
Doesn't rob battery due to higher power
Adjustable front and rear sights
Just performs at a 5 star level for an out of the box DMR
Only had one issue after using first time, kept cutting off, just found loose connection with fuse. Resoldered connections and good to go.
A little heavy so after a full day kinda sore but I got used to it no problem
Absolutely no cons with this gun after several weekend and thousands of rounds through it!
A REAL MUST HAVE FOR ANY COLLECTION!!!
"Had this rifle for maybe a month or so. I haven't brought it out for any skirmishes, but I feel in its prior, stock state, it would perform on par to slightly upgraded AEGs. As stated in earlier reviews, my barrel was filthy. I cleaned and polished it. There are no known hop-up chamber replacements, though I figure if the A&K uses a similar gearbox and magazine, it must line up a bit. I'll purchase the aftermarket A&K hop later to see if it can be easily MacGyver'd in. Externally, it's not the best. You got that by now. The KA version is not the prettiest. Oh well. I personally never cared about 1:1 replica as long as it looks the same at a glance and is sleek and clean. It looks like an SVD to me. Moving along... The stock box is fitted with a short motor, standard gears, 15-tooth stock piston and piston head, a weird extension between the piston and piston head to make up for the longer v2.5 cylinder, stock V7 cylinder head (inverted), odd tappet plate, V3-ish switch, plastic QD spring guide that will eventually break, 120 spring, and AK nozzle.
For the spring guide, I purchased an all-metal, bearing, QD spring guide. QD guides are a feature that make box upgrades loads easier. This becomes a must-have for boxes with high power springs. The new guide slips right in, but the original piece that screwed into the rear of the guide to stabilize it wasn't able to screw into the new guide. I remedied this with a regular screw and washers.
Alternatively, this could fit v3 spring guides well enough. You would still need to use a screw and washers to stabilize the new guide, as the gearbox lacks the cutouts that the guide wings would slip into.
The spring is a spring. Upgrade it. PSG-1 springs, AEG springs. I put a 140 AEG spring into mine,
With the included piston extension, It can use a standard 15 tooth piston/gear set in the long cylinder. This; however, doesn't utilize the full length of the cylinder. I've changed mine out for a 19-tooth piston/gear set combo. These 19-tooth parts can be found as upgrade parts for the L85 or SR25 which use the same long set-up.
Piston head is a piston head, Everyone has their preferences. Buy what would suit your goal for the gun.
The cylinder head can be swapped out for an upside-down v7 (M14) cylinder head.
The cylinder is from the v2.5 gearbox. Slightly longer. Again, may be labelled as L85/SR25/PSG-1 upgrade parts.
This rifle can use AK nozzles.
Haven't had a hand at replacing the tappet plate or wiring. Tappet looks vaguely like v7? (This is a guess) and the switch is v3 in form, though the way the trigger pushes it is slightly different. Again, I haven't fiddled with them.
The motor is a short type, commonly used in v3 (AK, G36, UMP, whatever).
Do your usual AoE correction, new o-rings, flat hop, sorbo, etc.
If it doesn't need to move, bolt it down.
If it could probably have an air leak, seal that sucker up.
Overall, the gun at its $120 deal was the best on the web at the time (I checked) and I don't regret my purchase. The rifle wasn't impressive stock, but what stock gun is? Every gun can be upgraded to outperform the others. It's a wonderful project for a cheap starting price that is lightweight, sleek, unique, and still intimidating. It has the option of semi and full. How could you go wrong with more rounds down range? About the only thing I dislike about the gun is the 50rd midcap (I prefer mids) and the difficulty of mag removal when the mag is loaded.
Additionally, I shaved the dust cover somewhat because it blocked the safety lever from clicking into place in "Safe." I slapped on the bipod made for the SVD. The clamp loosens periodically, especially with heavy movement. I dislike the lock. But I'm dealing because the only other bipod options are to get a rail or stud on this rifle somewhere or use a barrel-mounted bipod. I think the SVD bipod suits it, anyway. I opted for an AK side rail mount and a 3-9x40 scope. I knocked out the pin so I could push the mount further forward, as in its original position, the scope was all up in my business despite being mounted as far forward as possible on the rail mount. I did this because the POSP scope is left-offset and doesn't suit my south paw ways.
