Please note the following:

All .22LR Conversions AND all spare magazines are test fired on/in our OEM Firearms using Remington 40 grain, round nose/solid point, Hi-Velocity ammunition.  These firearms are maintained in the finest condition and replaced regularly to maintain OEM manufacturing specifications.  By doing this we have a certainty that they will work on properly manufactured / maintained customer's firearms.

Customers who may be experiencing a problem with one of our conversions are advised to refer to the included instruction booklet to assure they are following the very specific information.  If this does not alleviate the functioning problem they are MOST strongly advised to forward the receiver of their firearm (only) with the conversion unit AND all spare magazines so we may verify why the unit tested perfect on our firearm but is experiencing a problem on theirs.  Absolutely no modifications to the supplied firearm frame will be performed.  It is only for our testing AND verification of proper functioning before return of the conversion.

BE ADVISED if the problem being experienced is due to the customer not following instructions in the included instruction booklet or an anomaly of the customer's firearm, there will be charges for our verification of customer error or adjustment of our conversion to overcome the firearm's anomaly.

Any units sent for service/repair outside the ONE year warranty or without proof of original retail purchase within the ONE year, as noted above, will carry a minimum $50.00 service charge, charges for any parts required and $10.00 return shipping.  Invoice for these charges will be mailed for pre-payment before return of the unit.
