Mossberg® .22 Rifle Parts

The following listing includes the most commonly requested parts for the most commonly owned Mossberg® .22 caliber rifles. We carry many more parts for each of these models than we would have room to list here. On the flip side, while we try to be sure that every item for every model listed below is currently in stock, we are dealing with obsolete models as much as 60-plus years out of date. Original sights and bolts have become very scarce recently.  Calling us at 636-937-6401 is the best way to assure that we have what you are looking for. You may also inquire by e-mail to
vic@havlinsales.com. Please note that while models may be grouped here for pricing similarity and space, each model is distinctly unique and we must have the exact model number in order to fill your request, i.e., Model 42 and Model 42A are very different models. Parts may be good condition used or new production, and depending on item, fitting may be required by a qualified gunsmith to insure proper function and safety.

New Item!
Reproduction Targo RA1 rifle adapter and TT1 smoothbore extension
If you have a Targo missing the rifled or smooth bore extension, this is the low-cost solution. Faithful reproductions of the rare rifle adapter and smoothbore extension for the 1940s 42T, 42TR and 26T smoothbore Targo models.



Rollstamp: "MOSSBERG NO. RA1 RIFLE ADAPTER", knurled end, recess for spanner wrench, correct blue finish. Approx 4-7/8" long. Rifled bore extension designed for .22 rifle ammunition



Rollstamp: "MOSSBERG NO. TT1 TARGO TUBE", knurled end, hole for spanner wrench, correct blue finish. Approx 7-3/4" long. Smoothbore choke extension designed for .22LR shotshells

Note: Each tube can be identified as a reproduction by a small pin-punch proof mark on back of each tube located near the knurling to prevent mis-identification as an original.

BEST SELLER!  MOSSBERG .22 SCOPE MOUNT 
Now available!
No gunsmithing required!  Use any diameter scope!    

Mossberg side mount and screws – ONLY $26.50

For models 26B, 26C, 42A, 42B, 42C, 42M (all variants), 43, 44US (all civilian variants), 46A, 46B and 46M (all variants) and most Wards-Westernfield rifles side-tapped on 1-5/8” centers (made by Mossberg).  Mount conforms to curvature of receiver and features Weaver style top platform.  Note:  Approx 30% of military marked 44US rifles are not drilled and tapped for scopes.  Please check your receiver. We can provide D & T specs if you wish to drill and tap.

Will center any diameter scope directly over the barrel – no longer limits you to ¾” tubes.  Quality mount allows you to keep the iron sights in place.  Remove bolt cover, if present, to allow bolt to clear mount base. Add rings and scope of your choice.  Comes with two button sock mounting screws and Allen wrench.  $26.50 per mount. Ask about rings in high/medium/low rise for 1” and 30mm scopes for $22 extra, or use rings that came with your scope.

Scope rings (please specify high, medium or low rise, 1” or 30 mm) = $22/pair
