G&P M4CQB WOC "Special Forces 100M" GBB Airsoft Gas Blowback Rifle Challenge Kit (9.5" Barrel)
by Andrew R. Date Added: Sunday 17 November, 2013
This is a great kit. I spent about 2 1/2 hrs in total assembling it, and I am still testing it for durability and reliability. It would be nice if the standard G&P were available, I am sure I would have had less teething problems than I had with the KA magazines. Some upgrades and issues I have experienced.
1) it seems not all the parts were packed for the hammer bushings as I seem to have a few short. This was not a problem, as I just manufactured some new ones.
2) the BB loading finger on the nozzle got deformed, mainly due to issues with the KA magazine. I had to cut it off and manfuacture a new finger from steel, which was then pinned into place and works perfectly.
3) the nozzle retaining clip broke after a few shots, but it doesn't seem to detract from the performance of the gun.
4) the charging handle spring catch broke. This I can manufacture a rreplacement of once again so there's no major issue.
Other than these small issues (it DOES say, "challenge kit") the gun is awesome. 600 rounds per minute at about 400FPs on 0.25 BBs. The internals operate very well, and you just need to keep it clean and free of erant BBs and pieces of broken ones if they break during feeding. Accuracy is very good too, at 30 ft on full auto a 4 inch grouping is possible on a full magazine. The recoil is very lively and adds very much to the realism.
All in all excellent value if you like assembling this type of thing, are mechanically inclined and don't mind troubleshooting, modifying and upgrading this gun to exactly what you want.
