The BioMech Acculock Putter is the most comfortable and best armlock putter I’ve ever tried, by a wide margin. Everything about this is unusual, which might be ideal if you want to shake up your putting.
Armlock putting has been a hot topic in golf with some claiming that it’s an inherently easier way to putt. While there’s a common sense appeal to limiting the moving parts in the putting stroke, most armlock putters are nothing more than longer versions of standard putters. The BioMech Acculock is different – a putter that’s entirely designed around the armlock stroke. I tested one to see if this is the future of putting.
Do I need to state this obvious? This isn’t your granddad’s Bullseye. To start, the BioMech Acculock is big – approximately 4.5″ square. There’s also the color. The Acculock is available in black or silver, but when a putter looks this unusual, I think blue, pink, and burgundy are better options.
There’s also the small issue of the shaft being attached to the back of the head. That’s going to earn some sideways looks on the putting green. Finally, I’ll note the hole in the middle of the head which is surrounded by a larger indentation.
Here’s the funny thing about the Acculock: because nothing about it is conventional, it works. If you took an Anser and shoved the shaft into the flange, it would be a disaster, but this putter throws every convention out the window to be something completely original.
Before moving on, I need to mention BioMech’s Optical Alignment System. BioMech advises that the golfer put their dominant eye over the hole. From this position, they can use the perpendicular white top line and the divided sightline to aim. Also, because the shaft is out of the way, the golfer has an unobstructed view of the ball, putter, and path to the hole. In my testing, I found the BioMech very natural to aim, in part because of the open stance that the putter promotes.
Sound & Feel
The BioMech Acculock is milled from aerospace-grade aluminum. Aluminum putters typically aren’t my favorite when it comes to feel, but the Acculock isn’t bad. It’s firm with limited feedback, but it’s definitely not a deal breaker.
Impact is fairly quiet, but the sound of impact provides excellent feedback on strike quality.
BioMech built the Acculock putter around a particular method, so let’s first describe what that is. They advise a slightly open stance, a conventional grip (right hand low), the putter grip resting on the left forearm, and the left shoulder sitting naturally higher than the right. Per BioMech, this method “stabilizes the hands, arms, and shoulders,” engages the core muscles, and “reduces and/or eliminates hand, arm, and shoulder movements, resulting in more accurate putts.”
All that sounds pretty good, so I was eager to see what it did on the green. The first thing I noticed – and I can’t overemphasize this – is how comfortable the Acculock is to putt with. I’ve tried a handful of armlock putters and found them, at best, stressful on my wrists and forearms. With Acculock, I could putt all day. Not only does the grip rest on my forearm without any extra bending or flexing, the putter allows me to stand more upright. Additionally, the putter grip feels more secure in my forearm compared to other armlock putters, probably because it sits there so easily.
When I first took Acculock to the practice green, I had the typical new putter experience: made a lot of putts, then missed a lot, and finally went back to my normal level of putting. Nothing shocking, good or bad.
The next time I tested Acculock was indoors on a ten foot putting mat with a reduced hole. During this session, I was more focused on getting into BioMech’s recommended set up and using my shoulders and core to power the stroke. The results were unreal. I was making 8 or 9 out of every 10 putts into a 3.25″ hole.
I went back to the practice green with Acculock and continued to see impressive results. The only negative that I can report is that I needed some time to get a feel for distance control. I’d also note that if you gave me a life-or-death putt, I’d still reach for my normal putter because I haven’t had enough time with Acculock to build up the level of confidence I have in my gamer.
My ultimate conclusion on the BioMech Acculock putter is that it is easily the king of armlock putters. Additionally, I do think there’s something to be gained from this particular combination of method and putter. That said, it’s not an instant fix. You need to commit to the method and put in the work to make it automatic and to build your confidence with it.
If you’re thinking about making the switch to an armlock putter, you owe it to yourself to check out the BioMech Acculock. Currently, the putter is only available through the BioMech website, but the company does offer a refund if you find that it’s not for you.

I really like the looks of this. It just makes sense. Do you know if the wrist lock grips would work on it? I just detest the longer armlock, belly putters etc. Good review.
The grip on the Acculock is 17″. The Wrist Lock is 13.75″, according to the Super Stroke website. I don’t see why you couldn’t use the Wrist Lock on this putter, but it would be shorter, so your hands would be several inches higher up the shaft.
No photo of the armlock grip, but discussion about the grip and it’s benefits. Article seems incomplete without a full grip photo.
If you want to see a picture of the putter in use, you can click the link at the bottom of the review. There are several such pictures on the BioMech website.
I’m amazed that the article didn’t include a picture of someone using the putter!
Found the price on their website. $300-$330. I missed it in the article.
I recently purchased one of these and it works for me. I’ve not missed anything 6 ft or under in 4 rounds nor have I had any 3 putts. Takes some practice to get used to it and get the distance dialed in, but once you figure it out, it is almost like cheating. Definitely a more comfortable stance with no pressure on the lower back. I’ve tried to go back to my Evnroll putter because I do like the feel off the face better than the Accu Lock, but at the end of the day its about being comfortable, confident, and making putts…so the Accu Lock stays in the bag.
Excellent review, thank you!
Is this a putter you’d recommend for someone suffering from the yips?
Also, not the aluminum build – is she tinny at all like the L.A.B DF2?
I don’t claim to be an expert in the yips, but if you want a fresh start on your putting, this is certainly worth trying out.
