The Two Rifles Documented Here — a Deluxe Sporter, a Takedown, and the Suppressor Question

8.1 How This Volume Is Written

The first seven volumes are about the 10/22 as a pattern. This one is about two particular rifles, and it is written under three rules.

• Configuration is dated. Everything below is the configuration recorded in the owner’s inventory (last modified 17 September 2026) and confirmed as current on 19 September 2026. Rifles like these change; this volume says what was true then.
• Installed and planned are kept apart. The inventory marks parts “Installed,” “On Order” or “Pending.” Only “Installed” means fitted. “On Order” and “Pending” mean not fitted — in many cases the part is on hand, waiting. This volume never describes a planned part as fitted.
• Nothing is inferred. Where the inventory is silent, this volume says the configuration is not recorded.

No serial number appears here, for either rifle or for the suppressor.

8.2 The Two Rifles, Dated

Table 1 — 8.2 The Two Rifles, Dated

	Rifle 1	Rifle 2
Owner’s name for it	”10/22 DSP Blued Barrel"	"10/22 Takedown SS/SYN”
Model	Deluxe Sporter (Volume 3 §3.3)	Takedown, stainless barrel, synthetic stock (Volume 3 §3.4)
Barrel	18.5 in, blued	18.5 in, stainless
Approximate shipping year	2011	2017 or later
Manual	Ruger PM058	Ruger PM058
Bolt lock	Pre-2025 factory type, now replaced (Section 8.3)	Pre-2025 factory type, now replaced (Section 8.4)

The shipping years come from Ruger’s serial-number history table, which gives “the approximate first serial number shipped for the indicated year.” The Deluxe Sporter’s serial prefix falls between the first numbers listed for 2011 and 2012. The Takedown’s prefix is above the first number listed for 2017, where Ruger’s table ends; Ruger introduced the Takedown in 2012.¹² Ruger’s caution applies: numbers are not always used in order, and blocks may be built “out of sequence, sometimes years later.”¹

Both rifles predate model number 32000, so both are covered by Ruger’s PM058 manual, and both were built with the old two-handed bolt lock (Volume 2 §2.8). Neither has a rear cleaning port.

The Ruger catalogue numbers of the two rifles are not recorded.

8.3 The Deluxe Sporter, as Documented in September 2026

Installed (3):

Table 2 — Installed (3):

Part	Notes
Nikon P-Rimfire 2-7×32, BDC150 reticle, matte, 1 in tube	The mount it sits on is not recorded: the rail and rings below are both still on order. Optic theory: the Scopes dive; this reticle’s calibration and the magnification fix: the .22 Rimfire dive’s Volume 11 §11.3
Volquartsen Automatic Bolt Release	Pull-and-release; replaces the factory bolt lock inside the factory trigger guard (Volume 4 §4.2)
KIDD bolt buffer	Replaces the bolt stop pin (Volume 4 §4.3)

Planned — on order or pending, not installed (9):

Table 3 — Planned — on order or pending, not installed (9):

Part	Sheet status	Notes
Mack Brothers Lima suppressor	”Pending new federal rules”	Section 8.7
UTG Tactical Low Profile Rail Mount	On order
UTG AccuShot Picatinny/Weaver Medium Profile 1 in rings	On order
Magpul Hunter X-22 stock, “medium” cheek riser	On order	The standard, non-takedown stock (MAG548). Magpul sells no “medium” riser (Volume 4 §4.8)
Magpul M-LOK bipod mount	On order	For the shared Harris bipod
KIDD single-stage trigger unit	Pending	Brings its own auto bolt release (Section 8.5)
KIDD bolt handle, black, black Viton	Pending	Needs a KIDD guide rod kit (Section 8.5)
KIDD bolt, firing pin and extractor	Pending
Harris HBRMS 6–9 in swivel bipod with Pod Loc	Shared	Section 8.6

The Deluxe Sporter as documented is therefore still mechanically almost a factory rifle: factory barrel, factory bolt, factory trigger group with an aftermarket bolt lock in it, and an aftermarket bolt stop. The planned parts would replace the stock, the trigger group and the bolt — everything except the barrel and receiver.

8.4 The Takedown, as Documented in September 2026

Installed (9):

Table 4 — Installed (9):

Part	Notes
Mack Brothers Lima suppressor	Owner’s figure 41 dB — Section 8.6
UTG Tactical Low Profile Rail Mount
TPS 1 in low-profile rings, 0.785 in height	Height as recorded by the owner; TPS’s own specification was not retrieved
Nikon P-Rimfire 2-7×32, BDC150	The same model as on the Deluxe Sporter
Magpul Hunter X-22 stock, “medium” cheek riser	On a Takedown receiver this must be the takedown version, MAG760; the standard MAG548 does not fit (Volume 3 §3.4). Recorded simply as “Hunter X-22”
Magpul M-LOK bipod mount
Volquartsen Automatic Bolt Release
KIDD bolt handle, silver, black Viton	KIDD says its handle is used with the KIDD guide rod and spring kit (Section 8.5)
KIDD bolt buffer

Planned — pending, not installed (2), plus one shared:

KIDD bolt, firing pin and extractor	Pending
KIDD single-stage trigger unit	Pending
Harris HBRMS 6–9 in bipod with Pod Loc	Shared

⚠ A conflict with a published dive. The .22 Rimfire dive describes both 10/22s as wearing a full KIDD drivetrain — single-stage trigger, bolt, firing pin and extractor, buffer and handle — in its Volume 9 §9.6 and in the introduction to its Volume 11. By the owner’s inventory, as confirmed current on 19 September 2026, the KIDD trigger and the KIDD bolt group are not yet fitted to either rifle, and on the Deluxe Sporter the KIDD handle and the Magpul stock are not fitted either. This volume follows the inventory.

8.5 What the Plans Imply

Taken together with the makers’ own compatibility statements in Volume 4, the planned parts have consequences the parts list does not show.

1. The KIDD trigger unit retires the Volquartsen release — on both rifles. The Volquartsen release is a part inside the factory trigger guard. KIDD’s single-stage unit is a complete replacement guard with “auto bolt release installed.”³ When the KIDD units go in, the Volquartsen releases come out with the factory guards. That is not a problem — the function is preserved — but the Volquartsen parts will then be spares.

2. The order of fitting matters. Volquartsen states its release is “only compatible with Volquartsen and Ruger factory bolts and trigger guards … It is not compatible with other manufacturers’ parts.”⁴ Fitting the pending KIDD bolt to either rifle while the factory guard and Volquartsen release are still in it would put that release against a non-Ruger bolt, outside the maker’s stated compatibility. Fitting the KIDD trigger unit first, or with the bolt, avoids that intermediate state.

3. A KIDD handle comes with a KIDD guide rod. KIDD’s handle is specified for use “with KIDD guide rod & spring kit,” and KIDD notes that the factory handle is “permanently affixed” to its assembly.⁵ So:

• The Takedown, which has a KIDD silver handle fitted, presumably also has a KIDD guide rod — and the kit offers three springs, standard, 10% heavier and 10% lighter.⁶ Which spring is fitted is not recorded. It matters, because spring force is one of the two blowback tuning variables (Volume 2 §2.1), and the .22 Rimfire dive’s Volume 9 discusses exactly this spring choice for subsonic ammunition.
• The Deluxe Sporter’s pending black handle needs the same kit, which does not appear on its parts list.

4. Every KIDD bolt is a blowback change. The pending KIDD bolt weighs 6.5 oz by KIDD’s figure; the factory bolt’s weight is not published (Volume 4 §4.5). Fitting it changes bolt mass alongside a buffer and possibly a different spring. The first-rounds checks in Volume 5 §5.5 — fired case heads, rim strikes, feeding from a full magazine of the ammunition actually used — apply to each rifle after the bolt goes in.

5. The Deluxe Sporter’s walnut stock. If the Deluxe Sporter still wears its factory walnut stock (Volume 3 §3.3), the Magpul stock will replace it, and the rifle will no longer be visually a Deluxe Sporter. The factory stock is worth keeping with the rifle.

8.6 The Shared Parts

Three items appear on both rifles’ sheets and move between guns.

• Harris HBRMS 6–9 in swivel bipod with Pod Loc — recorded on both rifles as “sharing between rifles.” It is not part of either rifle’s configuration.
• Nikon P-Rimfire 2-7×32 BDC150 — the same model on each rifle. Whether these are two scopes or one moved between rifles is not stated on the sheet; each rifle’s row records one as fitted.
• Mack Brothers Lima — installed on the Takedown, and the “pending” suppressor on the Deluxe Sporter’s row. Whether the Deluxe Sporter’s entry refers to a second Lima or to the same one being shared is not recorded. The sheet notes the Lima is “no longer being made,” which matches what the .22 Rimfire dive’s Volume 10 §10.8 found. The owner’s inventory records 41 dB against the Takedown’s Lima. No maker’s page for the Lima could be found to confirm that figure or its test conditions, and as the .22 Rimfire dive says, a decibel figure of unknown method is useful for comparing the can with itself and nothing else.

The .22 Rimfire dive’s Volumes 9 and 11 cover what sharing one can across several hosts means in practice: a round count kept on the can, not the rifle, and a can-on/can-off zero offset recorded for each host.

8.7 The Suppressor Question in 2026

What changed. Public Law 119-21, signed 4 July 2025, set the National Firearms Act making and transfer tax to $0 for suppressors, short-barrelled rifles, short-barrelled shotguns and any other weapons, for applications from 1 January 2026. It did not reach machine guns or destructive devices, which still carry $200.⁷

What did not change. Everything else. A suppressor is still an NFA firearm; it is still registered; a Form 4 or Form 1 is still filed; fingerprints, photograph, background check and ATF approval before possession are all still required. The Suppressor Law dive’s Volume 3 sets it out line by line, including the April 2026 ATF package that removed chief-law-enforcement-officer notification and allowed joint spousal registration — some of whose items were proposals rather than final rules when announced.⁷ The purchase process is its Volume 4; Michigan’s position, where ownership and hunting use are lawful, is its Volume 7 §7.3.

What “pending new federal rules” might mean. The Deluxe Sporter’s row gives the suppressor’s status as “Pending new federal rules.” The sheet was last modified in September 2026, but the note may be older. Two readings fit the facts, and the sheet does not say which is meant:

• a transfer that was deliberately held back until the $0 tax took effect on 1 January 2026 — in which case the rule it waited for is now in force; or
• waiting for a further change — the Hearing Protection Act or the SHUSH Act, which would take suppressors out of the NFA’s registration regime altogether. Neither had passed when the Suppressor Law dive’s Volume 6 was written.

Which it is, and whether the Deluxe Sporter’s suppressor is a second can or the Takedown’s shared one, are questions for the owner, not inferences for this volume. If it is the same registered Lima, the NFA registration is of the suppressor itself and names no host rifle; moving a registered can between rifles in the registrant’s own possession is ordinary use, subject to the possession rules in the Suppressor Law dive’s Volume 8.

The prerequisite the sheet does not list: a threaded barrel. The Takedown can wear the Lima because its barrel is threaded — the suppressor is installed. The Deluxe Sporter is another matter. Ruger’s descriptions of the Deluxe Sporter give it no threaded muzzle, and Ruger’s 2003 parts list shows its barrel as the same blued part as the carbine’s.⁸⁹ Ruger’s manual reserves threaded barrels, protected by a thread cap or flash hider, for models “so equipped.”² The owner’s sheet records no threading on the Deluxe Sporter and no replacement barrel on order. Unless the barrel has been threaded or replaced — which is not recorded — the Deluxe Sporter cannot take a suppressor as it stands. The options are a threaded aftermarket barrel (Volume 5 §5.3) or threading the existing barrel in the lab. Ruger’s manual states the standard any muzzle device must meet: the correct thread pitch, and “verification that the muzzle device is mounted concentric to the bore,” because misalignment “can cause baffle strikes … and/or catastrophic failure.”¹⁰ It also carries the general warning against alteration of the rifle (Volume 7 §7.11). The concentricity of any threading done in the lab is the thing to verify with an alignment rod before the first shot; the How Suppressors Work dive’s Volume 7 covers the check.

8.8 What Is Owed

Photographs and measurements that exist nowhere in print, in order of value.

1. The bench method of Volume 6 §6.8, run on either rifle — one variable at a time, recorded. No controlled 10/22 accuracy data of this kind was found in any published source.
2. Buffer versus factory pin (Volume 4 §4.3). Feeding and, if a chronograph or high-speed camera is available, bolt behaviour with the KIDD buffer and with the factory bolt stop pin, same ammunition. It is the only way to test Sefried’s patent claim against the buffer makers’ claims.
3. Factory bolt and KIDD bolt on a scale, when the KIDD bolts go in — the factory weight is published nowhere.
4. The Takedown’s five-reassembly result (the test is in the .22 Rimfire dive’s Volume 11).
5. Photographs: each rifle full length as configured, dated; the Deluxe Sporter field-stripped; the Takedown separated with the Lima on the barrel half; the Takedown’s joint from below.
