The latest project from SRU GBB is not a new conversion kit for a gas blowback airsoft gun but for the best selling Tokyo Marui VSR-10 System. You can give your VSR-10 a very futuristic look with the SRU SR-SNP-10 Kit which lessens the overall length of the VSR-10 whilst maintaining the same barrel length. They are now taking pre-orders with free shipping right now.
