UK Law ?

[452Varmint]

Would it be legal to build a pistol using a 2250 stamped main tube ?
Pistol grips, no shoulder stock, sub 6ft/lbs

I probably have enough parts to assemble a pistol but obviously want to keep it legal, any issues i can always try to swap the 2250 tube for a 2240 tube but i like the idea of a longer tube and adding a 2250 forend to make it look like the old SSP2-250.

not a problem provided it was under 6fpe
