The Elftmann Tactical Rifle Conversion Kit (TRCK) is a really fun product to own. It is difficult to find, but easy to get if you are quick enough to get one of the last 15 or so the manufacturer still has in stock. I write this review from the perspective that a bullpup stock on a 22 is really a “novelty item” that is intended to enhance an already functional piece of equipment both visually and practically. I personally think it is worth the price I paid for it and would have paid another $25 more for it. Compared to the reviews I have read of competing bullpup alternatives, the TRCK is a solidly built, well thought piece of equipment with only a few small drawbacks that I will cover in more depth below.
I was grinning from ear to ear when I finally put some rounds down range through the TRCK. The trigger is heavy, but not markedly heavier than the stock Marlin trigger. In my opinion the trigger pull is acceptable and not too far off from many Mil-Spec triggers I’ve pulled in my career. I don’t have a gauge, so I can’t give you an accurate weight for it.
The TRCK took little more skill to install than the ability to use a screwdriver and Allen wrenches (since it’s my name I tend to capitalize Allen in all uses), which you can read more about in my installation walkthrough. As I mentioned there, I added some hardware store fasteners to properly hold down the top rail. This is a pretty important step since you have to have this rail to get your optics to stay in place and maintain zero. The iron sights are unusable with the stock installed because the butt plate of the stock sticks up and blocks them. This isn’t a huge deal for me, since I really prefer a red-dot anyway. If you want back-up irons, there isn’t really enough rail space. There’s also too much vertical separation (and therefore parallax) to mount a scope high off the rail. I couldn’t get the Redfield (mounted on the Larue LT-104) adjusted down enough to zero at 50 yds. Since that’s about the limit of 100% effective 22LR range for me and I knew going in that I needed to mount an optic lower on the rail, I put one of my Aimpoints on the rifle and zeroed at 25yds. I didn’t have any problem zeroing the Aimpoint at that range.
The major difference between the Elftmann and the other alternatives I found before purchasing is that this kit is made of metal. It feels as solid as an AR when you’re done and sounds the same when it comes into contact with something. It’s definitely not a plastic piece of junk. I really want to buy a couple more just to try out in the 10/22 and Marlin 795 versions.
My main drawback with this product is reliability. After putting a couple hundred rounds through the rifle with this setup, I’m a bit concerned about the long-term functionality of the trigger linkage and internal assembly (including the safety). It’s very rough and occasionally hangs. If this was a means of self-defense, I would not use it at this point. I hate to say that… because I can carry a ton of ammunition and it is only 26 3/4″ long, but if you don’t KNOW it will fire every time, the it CAN’T BE DEPENDED UPON to fire every time. Really too bad. But this thing is fun. If you get one, feel free to send me pictures and I’ll post them for you here.
