It was BASC's view in 2010. You need to look at what constitutes an "air weapon"
My view on it.
What is an air weapon.
Specification contained in Section 1 (3) (b)
It cannot be over 12FPE for a rifle and 6FPE for a pistol. It must also not be a prohibited weapon ie. the barrel must be over 30cm and the overall length must be over 60cm. The measurement criteria was an addition to the Act in 1997 effectively banning "short weapons"
To avoid banning air pistols Section 5 (1) (aba) excludes "air weapons". Looking at the above a rifle over the measurement criteria and under 12FPE is classed as an "air weapon". A rifle over the measurement criteria and over 12FPE is classed as a Section 1 Firearm. If the rifle is under 12FPE and under the measurement criteria it is a prohibited weapon as it doesn't qualify as an "air weapon" under the rules.
A "short weapon" can only qualify as an "air weapon" if it is less than the measurement criteria and if it is under 6FPE. Then it's excluded from Section 5.
Barrel length measurement is specified in Section 57 (6) (b)
I understand there is some form of agreement that a permanently fixed shroud/stripper/etc can be included in the barrel length. AA are currently checking this with their Trade Association.
