Fred Zeglin released two titles in his new series of instructional books for anyone who wants to understand how guns work.  Tailored to students of gunsmithing, whether you are a hobbyist or a professional Zeglin bring over 3 decades of gunsmithing and teaching to the table.  These books are clear and concise detailing specific subjects.

Lee Shaver, well known gunsmith and writer said about these books, “Frankly, some of that information on headspacing should be emblazoned on the wall behind the counter of every gun shop in the country.”

The first two titles are “Understanding Headspace for Firearms” & “Chambering for Ackley Cartridges”.  The third title came out in the first quarter of 2018, Zeglin joined forces with Bench Rest Gunsmith, Gordy Gritters for this book which is titled, “Chambering Rifles for Accuracy”.

Many other titles are planned for this series and Zeglin plans to tap other experts in the Gunsmithing field to aid in producing high quality, trustworthy instruction for any budding gunsmith.


Ron Pearson, Grandson of P.O. Ackley wrote, “Thanks for the booklet, Looks like a great series.”
