PETE'S PILLARS | USA-MADE PRECISION CHASSIS COMPONENTS
Move the Weight. Own the Balance.
A competition rifle should settle where you put it. Pete's Pillars M-LOK Exterior Forend Weights add a serious 12.3 ounces per pair in compact, USA-made steel modules built for shooters who want better balance, steadier supported positions, and more control over how their rifle tracks through the shot.
When you're shooting PRS, NRL22, or long-range centerfire, the rifle's balance matters just as much as its overall weight. Mass placed along the forend changes how the rifle rides a bag, loads against a barricade, and returns to target. Our 12.3 oz M-LOK exterior forend weight pair lets you put meaningful weight where it works, rather than adding bulk everywhere.
Twelve Ounces That Actually Work for You
Each weight is approximately 6.15 oz, giving you 12.3 oz (0.77 lb) in a complete pair. Position the set along compatible M-LOK slots to tune forward bias and help the rifle settle into a more consistent supported position. That additional mass can make recoil feel more controlled and make it easier to stay with the sight picture for follow-up shots.
The difference between a rifle that's simply heavy and one that's balanced is where you place the weight. Whether you're dialing in a compact rimfire chassis or a dedicated centerfire competition rig, these are purpose-built tuning tools—not decorative add-ons.
Steel Tough Enough for Barricade Work
We machine these weights from USA-sourced cold-rolled steel, then case-harden and black-nitride them for a durable, professional finish. Their compact exterior profile does more than build mass: it gives the side of your chassis a tough, replaceable contact surface for barricades, obstacles, and other hard shooting positions.
Let the weight take the scrape, not your expensive chassis. The steel modules are built to work hard, look right on a serious precision rifle, and keep doing their job every time you change positions.
Build a Better-Balanced Rifle with Pete's Pillars
Running an MDT Oryx? Our Pete's Pillars Oryx Rear Buttstock Weight with QD Cups adds approximately 7.3 oz at the back to complement front-end tuning. Add MDT Oryx M-LOK Side Panels where your chassis needs extra mounting positions, and you can tune front and rear balance with purpose.
For a dedicated CZ 457 competition rifle, the XLR Element 4.0 Chassis offers M-LOK mounting along its precision-focused forend. A heavyweight setup, such as a Lilja 26-inch CZ 455/457 .900 Match Barrel, makes careful front-to-rear balance even more important. These are the details that turn a collection of premium parts into a rifle that feels composed on target.
We also carry MDT M-LOK Exterior Forend Weights and MDT Exterior Forend Weights with QD Cups for shooters who prefer a different exterior configuration. Building around the ACC Premier Gen2? The MDT ACC Premier Gen2 Forend Tip Weight is another way to fine-tune forward mass using a chassis-specific part.

Frequently Asked Questions
Weight, balance, M-LOK fit, and how to make the most of your chassis.
How much weight does a pair add to my rifle?
The pair weighs 12.3 oz total—about 6.15 oz per weight. It is a substantial amount of steel in a compact package, and mounting it farther forward can make a noticeable change in how a rifle balances.
Will these help my rifle settle on barricades and track recoil?
That is exactly what they are made for. Added mass at the right location can help the rifle sit more firmly on a bag or barricade and move less through the shot. Position matters: the best setup is the one that puts the balance point where you want it.
Will these fit my MDT, XLR, or Oryx chassis?
They attach to compatible M-LOK mounting slots, so the key is having enough usable slot space where you want the weights. XLR Element 4.0 offers M-LOK mounting. On an MDT Oryx, the M-LOK side panels are a useful way to add the mounting positions you need.
Can they protect my chassis from barricade wear?
Yes. The steel weights double as exterior contact surfaces, taking the bump and scrape when you load the rifle against a barricade. That is a welcome bonus when you would rather put the wear on a replaceable accessory than your expensive chassis.
How do these compare with MDT exterior forend weights?
Our Pete's Pillars pair adds 12.3 oz and uses USA-sourced machined steel with case hardening and black nitriding. MDT also offers exterior M-LOK weights, including configurations with integrated QD cups. Both are useful ways to place mass exactly where you need it.
Should I add forend weights to a rifle with a heavy bull barrel?
It depends on where the rifle balances now. A heavy 26-inch bull barrel may already put plenty of weight out front. If you need even more forward bias, these weights are an easy option; if it is already nose-heavy, look at moving weight rearward instead.
What comes in the package?
Two Pete's Pillars steel exterior forend weights and the M-LOK mounting hardware needed to install them on a compatible mounting surface. No separate hardware kit required.
