Universal Weight-Tunable ARCALOCK Rail
$165.00
ARCALOCK has been a huge success since its release in July of 2018. As the rails have become more popular, we have also seen the rise in popularity of rifle weight kits. With the introduction of the Manners TCS stock in late 2019, we designed and built an ARCALOCK weight system, and are ready to make it available to the general public. This is the 14.25″ Universal ARCALOCK Rail!
WHAT WILL IT FIT – Lots of things. We anticipate this will fit about 98% of Manners PRS1, PRS1, T2A, T2A GAP, T4A, T4A TEAM and T5A stocks. If you’re not sure if it will fit your rifle, you can use the hole spacing print AVAILABLE HERE and some basic common sense to figure it out. We made this as universal as possible, while still retaining weight tuning capability. These kits will come with t-nut hardware to add attachment points if your factory-installed attachment points do not line up with our mounting slots.
WEIGHT – The bare rail weighs just over 6oz. With all 5 weights in the rail, the weight ends up at about 23.6oz. Each weight weighs 3.5oz.
THICKNESS – These rails are .400″ thick. For reference, our standard 14″, 12″ and 10″ Universal ARCALOCK rails are .270″ thick.
FINISH – Rails will be black hardcoat anodized, and the weights will remain raw brass.

I purchased three of these for my two Manners PRS-1 and CS2 stocks since my rifles were rear heavy. The weight of these rails helped balance the rifle tremendously. I bought the kit with all five weights and ended up using them all. In addition, the added weight has helped tame recoil a bit more.

A nice touch to the standard arca rail. I put it on my Graboe Ridgeback stock it fits perfect. I left all five weights in because I like heavy a rifle and it balances very nice.

This is really a must have item for competition. Its very important to have the rifle balance about 4″ in front of the magwell and this product is a big help. Its also amazing to see how not only the total weight on the rifle is critical to mitigate recoil but where that weight is placed. I give this one 10/10 stars.

Great product. The finish is beautiful, not a flaw in it. My only complaint would be the lack of longer screws for the T-nuts and a shorter action screw, one long enough to compensate for thickness of rail. Granted, I put this on a Bergara HMR pro and I believe these rails were more geared to fit the manners stocks. But I still got it to work and it works great. Worth every penny, would recommend and will buy again when I get my manners stock.

Hey Austin, we chased the “perfect length action screw” for a while, but ultimately opted for one that’s as long or longer than anyone needs as every stock maker or bottom metal manufacturer seems to be a little different on length. There was unfortunately no perfect answer.

The design and quality of this ARCA lock rail is excellent. Added 2 front weights in rail and the Front MPA weight Installed on a Matrix MAP chassis and balance point is 3″ in front of mag. Great quality hardware included. Best in class products!!

Well made. The interchange weight system is perfect for creating the perfect balance point of your rifle. It takes a little time to get it perfect but worth the effort.

Quality of arca rail is great. The action screws supplied were not the correct size, (did not thread into my action). The weight of this rail was not enough to balance my rifle, it would be nice to have heavier weights.
Hope this helps.

Hey Nowell. To fit the largest number of actions possible we include an action screw compatible with Rem 700 (and clone) actions. It would be really implausible to include screws to fit every action out there.

The Universal Weight-Tunable Arcalock Rail is a great addition to a rifle to gain the proper balance for barricade shooting. Area 419’s products are top notch in quality and design.

I have the same rail on all of my rifles

Some modification may be required. I am using a Manners PRS2 with Hawkins bottom metal. The radius where the mag well meets the action screw hole location was causing the rail to not sit flush against the forearm. I had to file away at the rail to make clearance. Also, I chose to not mount the rail using the action screw and using the hole just ahead of the action screw one. If you choose to do that, you will need to install a t-nut just in front of the action recoil lug which is a thick part of the barrel channel. I went to ace hardware to get longer screws for this to avoid going super deep with the counter sink. I hope I don’t run into any bad effects from doing this, everything’s been working great so far.

I put the weighted rail on my back up rifle/trainer so it matches the weight and feel of my match rifle. I mounted it to a first gen XLR Element (that chassis doesn’t come with a rail) the supplied hardware was perfect & bolted right up. Now my 1st Gen XLR Element chassis matches my XLR Envy Heavy in rail length and rifle weight and balance. So far I’m 10-10 with all 419’s products!

This is THE ticket. Get the weight in the right place and fire away. I have noticed a great reduction in recoil as well as a really nicely felt impulse.

Added the Area 419 weighted tunable arca rail to my Bergara HMR Pro rifle and absolutely love it. It was fairly easy to install. Just one email to customer service with a question that they answered right away. I love the fact that this shifted the center of balance for the rifle to just in front of the front action screw.
Previously it was stock heavy and center of balance was over the trigger which contributed to significant muzzle rise while shooting. Muzzle rise/flip is non-existent now. I used all 5 weights and love it. I would highly recommend this product.
