Lancer tactical CO2 conversion kit for LT-20 M82 sniper

I brought this due to the charging pull on this gun being hard, to say the least, I unfortunately found that the piercing valve for the co2 capsules was missing when it was delivered and genuinely expected a delay due to shipping being expensive for such a small item but a replacement was sent by the next post, no questions, blame or delays, I fitted this into the Barrett and what a difference, the loading is now an absolute pleasure, it even sounds more powerful when fired. Top retailer, I have since brought other items and continue to feel like a valued customer with fast delivery and stock of products hard to find elsewhere.
