We also have a special offer on the CMMG Evo 25Rnd .22LR Mags. These are the grey polymer versions with solid green followers, they work perfectly in SIG 522, Spikes Tactical and CMMG Rifles.
They don't have the bolt hold open feature and operate just like the Black Dog Mags. They are on offer at £24.00 each inc VAT + shipping.
Cheapest mags in the UK.
If you don't like the grey then they can be easily dyed using black (or any colour) RIT dye and warm water. Much better than spray painting and the mag stays the same size.
