Frequently Asked Questions
Q: When can I expect my order to ship?
A: Most in stock products will ship within 24 business hours. In rare situations of increased demand or production delays, orders may take longer than 24 hours to ship but if an item will be delayed longer than 3 business days, a representative will reach out to you unless otherwise denoted on the site.
HTA MBS 95:
Q: My new MBS 95 is really hard to take apart/slide together. Is this normal?
A: This is normal. When these parts are brand new and unused, they will have much of the stress from the manufacturing process still present in the structure of the polymer. This internal stress relaxes naturally with time through a process called "creep" and within a few months of being on the rifle, these stresses will have completely relieved on their own.
Heat will speed this process up greatly as well, since heat reduces the time curve for this creep to occur dramatically. Heating the upper stock portion to 200 F in an oven for 10 minutes and then sliding onto the rifle and lower while hot will anneal the polymer and reset it in the shape of your rifle. This is a simple and effective way of relaxing the polymer chains just enough to ease the assembly process. Using lubricants can also assist in the assembly process.
Q: Why I can't get my Hi Point Carbine™ action into/out of the MBS lower stock?
A: The Hi Point Carbine action must be closed and in "safe" to remove or install into the MBS lower stock. The action can be closed by removing any magazine, checking and clearing the chamber, and then pulling back on the action/bolt until it releases and closes. If the action is in the lower already, the takedown pins must be installed to prevent the action from sliding as the bolt is pulled. Once the action is closed, the safety can be moved to the upward "safe" position and the action either installed or removed from the lower stock.
Q: My bolt is locked open and the charging handle feels "disconnected"?
A: The Hi Point has a last shot hold open feature which locks the action open on an empty magazine. Our stock has a non-reciprocating charging handle, meaning the handle does not move with each shot and is not directly connected to the bolt, similar to an AR-15 charging handle.
Like an AR-15 charging handle, when the bolt is locked open, the charging handle will feel "loose" or "disconnected" when pulled until it reaches the back of the handle's full stroke, at which point it makes contact with the bolt. At this point, and with an empty magazine removed, the handle can be pulled all the way back to release the bolt. The Hi Point Carbine has a stiff action spring, especially in the larger calibers like .40, .45 and 10mm so it can take a considerable amount of force to release the bolt on these calibers. Again, make sure the empty mag has been removed or it will not release.
Q: How can I tell if my 10/22 barrel is long enough to have a legal length rifle (26 inches) when installed in the 90/22?
A:MOST10/22 factory barrels are of legal length. These include 10/22 carbine barrels that are considered 18 1/2 inches long. The HTA 90/22 is a bullpup style stock, which will shorten most 10/22 rifles to within 1/2 of an inch of the legal minimum length by moving the receiver and barrel rearward relative to a traditional stock. It is still very important, however, to check your rifle for length before purchasing the HTA 90/22 to avoid potential legal issues.
The Bureau of Alcohol, Tobacco, and Firearms (ATF) requires a minimum overall length of 26 inches and a minimum barrel length of 16 inches on all rifles. YOU MAY NOT COUNT DETACHABLE MUZZLE DEVICES TOWARDS BARREL AND/OR OVERALL RIFLE LENGTH. The ATF does not consider removable barrel attachments as part of a barrel and therefore you must measure from the muzzle crown, not the end of a flash suppressor, muzzle break, etc that can be unscrewed. However, welded or integrally machined, non removable barrel attachments DO count towards barrel and overall length. It is a felony to be in possession of a rifle that does not meet these requirements, without having gone through the proper channels first. High Tower Armory is not responsible for legal fees and other expenses resulting from failure to properly check the length of your rifle, both before purchase and after installation. It is also the end user's responsibility to check their local laws and regulations regarding the legality of this stock.
There are two methods for verifying that your rifle will reach the minimum length in this stock. The first method is to measure from the muzzle of the rifle (not including a removable muzzle device) to the point the barrel enters the receiver. In other words, measure the amount of barrel that is exposed. This length must be at least 17 1/4 inches.
The second method requires you to measure your 10/22 from the butt end of the receiver to the muzzle (not including a removable muzzle device). This length must be at least 23 3/8" inches for a legal length rifle.
High Tower Armory, LLC also highly recommends checking the overall length of your rifle once a HTA 90/22 kit is installed, to further verify the legality of your rifle.
Q: Will the HTA 90/22 work with .920 bull barrels?
A: Yes, any barrels with a .920 diameter will fit in the 90/22, as long as they are of legal length.
Q: Will the HTA 90/22 accept aftermarket magazines?
A: Yes, many aftermarket high capacity magazines will fit in the HTA 90/22. However, some magazines, including tear-drop mags, drum-mags, and Butler CreekTMmags that have protruding knobs for linking two mags together, may not fit into the 90/22 mag-well. EagleTM,Shooter's RidgeTM, Ruger factory rotary magazines, and Ruger BX-25TMmagazines are a few examples of magazines that will work in the HTA 90/22.
