So... I can do a quick "Early Review" which may help anyone considering one of these. I might do a video later too.
I am going to get the bad out of the way first. I want to do this, because I really would recommend one of these as a very nice alterative to an NFA firearm.
The Bad...
1.) My personal opinion, its a tad too heavy for practical use. All of my weapons are purpose built. Every one is also expected to be capable of saving my life or feeding my family. Understanding this, my first complaint my not apply to many, but if I need to hump any distance or use it for extended durations, ounces make huge differences for someone with disabilities or 60 lbs of extra gear.
2.) It doesn't work with my SIG 516 lower.
The problem is, unlike many AR15/M4 clones, the SIG 516 has quick disconnects built into the frame for a QD sling. The design of the MOD stock is excellent as far as looks and fit go... but the QD sling mount gets in the way. I would have to grind the frame... which is not happening.
This obviously is not by any fault or flaw with the design... its just a bummer I felt was worth mentioning for those SIG owners out there.
The Good...
1.) My personal opinion, its heavy. Yes, my first negative is also a positive. One of the problems shooters face with automatic weapons is control. I think the weight associated with this rapid fire modification will help some new rapid fire shooters.
2.) The looks of the new MOD stock are outstanding compared to the previous generations.
3.) There are QD sling mounts on both sides.
4.) It has an adjustable length.
5.) There is a friction brake that locks the stock rock solid in place for precision shooting.
6.) The tolerances are way better. Everything is snug. No rattling. When its locked into slow fire / precision shooting, even without the friction brake engaged, it doesn't move.
7.) The rapid fire switch is built into the pistol grip for easier access.
8.) The rapid fire switch is much easier to use, allowing for much faster switching between rapid fire and precision shooting.
9.) Pay to play on a machinegun is going to start around $30,000+, you have NFA rules apply and they aren't legal to own in every state. This product is only $300, no special registration or taxes. Legal to own in all 57 states (Obama reference... LOL).
10.) Most importantly... when I dump a 30 round magazine in 3 seconds, I smile on the inside.
All in all... great product, but for my purposes, I'm going to put together a purpose built lower for play time. The average firearms owner should have no problem using this as a full-time setup if they are in better health than me or aren't packing a heavy load while using it.
I'll gladly bring my DSLR to help capture the moment.
